Description

Update the documentation for pillarbox-analytics.

Changes made

• Update PillarboxAndroidLibraryPublishingPlugin to support loading module documentation from either Module.md or docs/README.md.
• Update docs/README.md to work with Dokka (mainly removing images) and improving wording and samples.
• Remove Module.md.
• Update the KDoc for every public class/method/interface.
• Make TCEventExtensions internal. I don't think this was meant to be public. Let me know if I should change it back.

Checklist

• APIs have been properly documented (if relevant).
• The documentation has been updated (if relevant).
• New unit tests have been written (if relevant).
• The demo has been updated (if relevant).
