Effect module: support setting effects to concat media items

[Romantic-LiXuefeng]

1. Is there a way to adding different effects for each media item when playback concat media items?
2. Is there a way to adding effects for single media item with clip time(start time ~ end time)?

Hello, we are planning on supporting (1) later this year, and for (2) you can try using this class to wrap an effect:

https://github.com/google/ExoPlayer/blob/909e241472b0ac9d8e462ccf89fbbfe731cbfcb3/library/effect/src/main/java/com/google/android/exoplayer2/effect/TimestampWrapper.java

(the linked class may only exist in the dev-v2 branch)
