Add getBytes() method to PlatformFile

[vinceglb]

I added back the useful method getBytes() that was here before to PlatFormFile with the exact same logic as before, except for Android where I added the fix from @shubhamsinghshubham777 proposed in this PR #104 that fixes #107

Do you want to be a maintainer? I will ask @Wavesonics, he usually responds on Kotlin's Slack

Personally I dont use this library, there was just my pet project, which used it but I have abandoned that.

[vinceglb]

I thought about it and I'm really interested!

I'm motivated to help this project grow. It will be my first time as a maintainer. I think I'll need a bit of guidance at first.

Some of the questions I have:

• What are your expectations of me?
• What are my obligations?

[shalva97]

That's great 🚀

Are you on Kotlin's Slack? we could disscus it there

[vinceglb]

Yes! My name on Kotlin Slack is Vincent Guillebaud

Any news about merging this PR ?

@vinceglb this looks good to me. I have actually been waiting for this to be merged before merging #100 as was mentioned in Slack (it might have happened before you joined), I didn't realize you were waiting on my review.

Is removing the strict visibility modifiers i.e. removing public something that was talked about? I don't personally mind and this was done before I joined, but it was obviously added explicitly.

[vinceglb]

The public keyword adds a lot of warnings in the IDE since it's a "Redundant visibility modifier". So I decided to remove it.

By default, everything is public. If we want to keep something internal to the module, we can explicitly use the internal keyword. But the public keyword is redundant by default.

[santiwanti]

There is a setting to set explicit visibility modifiers which means that public has to be specified explicitly. I think that was set previously. maybe it was removed in which case we can remove the public modifier

[shalva97]

Usually it is a good practice to have them explicitly specified for libraries. There was explicitApi() call in Gradle file but seems to be removed in the below commit, so now IDE thinks those visibility modifiers are not needed.

I think it should be added back
