Migrate Java files to Kotlin (#49)

This PR migrates the remaining [Java
files](https://github.com/search?q=repo%3ASRGSSR%2Fsrgdataprovider-android++language%3AJava&type=code)
to Kotlin. Each file is migrated in a dedicated commit.

To ensure that this doesn't break usages from either Java or Kotlin
clients, I've created the following simple classes. They do not test the
behavior, only that the API of each class remained the same.
```kotlin
package ch.srg.dataProvider.integrationlayer

import ch.srg.dataProvider.integrationlayer.data.remote.Quality
import ch.srg.dataProvider.integrationlayer.data.remote.Resource
import ch.srg.dataProvider.integrationlayer.data.remote.StreamingMethod
import ch.srg.dataProvider.integrationlayer.request.IlHost
import ch.srg.dataProvider.integrationlayer.utils.IlUrn
import ch.srg.dataProvider.integrationlayer.utils.StreamComparator

class KotlinUsages {
    fun ilHost() {
        IlHost.PROD
        IlHost.TEST
        IlHost.STAGE
        IlHost.MMF
        IlHost.MMF_PUBLIC
        IlHost.PROD_SAM
        IlHost.TEST_SAM
        IlHost.STAGE_SAM

        val ilHost = IlHost("custom-host", "my.il.host.com")
        ilHost.value
        ilHost.name
        ilHost.hostUri
    }

    fun streamComparator() {
        StreamComparator.SCORE_NOT_SUPPORTED

        val resource1 = Resource(url = "https://www.rts.ch/", quality = Quality.HD, streamingMethod = StreamingMethod.HLS)
        val resource2 = Resource(url = "https://www.srgssr.ch/", quality = Quality.SD, streamingMethod = StreamingMethod.DASH)
        val streamComparator = StreamComparator(emptyList(), emptyList(), emptyList(), false)
        streamComparator.compare(resource1, resource2)
        streamComparator.score(resource1)
    }

    fun ilUrn() {
        IlUrn.ASSET_VIDEO
        IlUrn.ASSET_VIDEO_SET
        IlUrn.ASSET_AUDIO
        IlUrn.ASSET_SHOW
        IlUrn.ASSET_GROUP

        IlUrn.isUrn("")
        IlUrn.format("", "", "")
        IlUrn.isAudio("")
        IlUrn.isVideo("")
        IlUrn.getId("")
        IlUrn.getAssetType("")

        val ilUrn1 = IlUrn("")
        val ilUrn2 = IlUrn("", "", "")

        ilUrn1.bu
        ilUrn1.assetType
        ilUrn1.id
        ilUrn1.isAudio
        ilUrn1.isVideo
        ilUrn1.isShow
        ilUrn1.equalsToString("")
    }
}
```

```java
package ch.srg.dataProvider.integrationlayer;

import java.util.Collections;

import ch.srg.dataProvider.integrationlayer.data.remote.Resource;
import ch.srg.dataProvider.integrationlayer.request.IlHost;
import ch.srg.dataProvider.integrationlayer.utils.IlUrn;
import ch.srg.dataProvider.integrationlayer.utils.StreamComparator;

public class JavaUsages {
    void ilHost() {
        var prod = IlHost.PROD;
        var test = IlHost.TEST;
        var stage = IlHost.STAGE;
        var mmf = IlHost.MMF;
        var mmfPublic = IlHost.MMF_PUBLIC;
        var prodSam = IlHost.PROD_SAM;
        var testSam = IlHost.TEST_SAM;
        var stageSam = IlHost.STAGE_SAM;

        var ilHost = new IlHost("custom-host", "my.il.host.com");
        ilHost.getValue();
        ilHost.getName();
        ilHost.getHostUri();
    }

    void streamComparator() {
        var scoreNotSupported = StreamComparator.SCORE_NOT_SUPPORTED;

        var resource1 = new Resource(); // This doesn't compile, but the goal is just to see if calls on `StreamComparator` are fine
        var resource2 = new Resource(); // This doesn't compile, but the goal is just to see if calls on `StreamComparator` are fine
        var streamComparator = new StreamComparator(Collections.emptyList(), Collections.emptyList(), Collections.emptyList(), false);
        streamComparator.compare(resource1, resource2);
        streamComparator.score(resource1);
    }

    void ilUrn() {
        var assetVideo = IlUrn.ASSET_VIDEO;
        var assetVideoSet = IlUrn.ASSET_VIDEO_SET;
        var assetAudio = IlUrn.ASSET_AUDIO;
        var assetShow = IlUrn.ASSET_SHOW;
        var assetGroup = IlUrn.ASSET_GROUP;

        IlUrn.isUrn("");
        IlUrn.format("", "", "");
        IlUrn.isAudio("");
        IlUrn.isVideo("");
        IlUrn.getId("");
        IlUrn.getAssetType("");

        var ilUrn1 = new IlUrn("");
        var ilUrn2 = new IlUrn("", "", "");

        ilUrn1.getBu();
        ilUrn1.getAssetType();
        ilUrn1.getId();
        ilUrn1.isAudio();
        ilUrn1.isVideo();
        ilUrn1.isShow();
        ilUrn1.equalsToString("");
    }
}
```

These should work the same way on the `master` branch and in this PR.
