v0.98

• AVI container support (work of dburckh, google/ExoPlayer#2092). May not work with OpenDML files (dburckh/ExoPlayer#8).
• Other improvements

-legacy version is a work around for limited file access on Android TV 11+ (#248). (It uses different package id - com.brouken.player.legacy - so this version won't be updated by Google Play.)
