feat: implement opacity to control visibility of subtitles (#3583)
* feat: implement opacity to control visibility of subtitles

implemented per discussion on https://github.com/react-native-video/react-native-video/issues/3579

updated docs and linked onTextTrackDataChanged to the subtitle style to clarify intent on how to control visibility.

* chore: update type so that we use a union of 0 1 vs any number

* chore: run ktlint to get rid of white spaces

* feat: add ability to have range of numbers for opacity; while, 0 will still not render the subtitles.

added util function for safeGetFloat

updated types

* feat: add ability to suppress subtitles with opacity 0

add data structure for subtitle styles for extensibility

* chore: run yarn check-ios

* chore: update documentation to clarify differences between android and ios

* Update android/src/main/java/com/brentvatne/exoplayer/ExoPlayerView.java
