Hello and thanks for the great library :)
I've faced an issue when using ProgressiveDownloader and HlsDownloader from ExoPlayer 2.16.1.
If they failed to perform downloading due to not IOException, CacheWriter in them never calls dataSource.close() (sources: 1, 2, 3) and because of that CacheDataSource remains opened and never calls Cache.releaseHoleSpan() -> CachedContent.unlockRange(), so CachedContent becomes blocked until the app restart.
Also I can't close data source manually, because I don't have an access to it in the XxxDownloader.
Example:
java.lang.IllegalStateException: Can't resolve source!

at com.google.android.exoplayer2.offline.DefaultDownloaderFactory$$ExternalSyntheticLambda0.execute(Unknown Source:0)
at com.google.android.exoplayer2.offline.ProgressiveDownloader.download(ProgressiveDownloader.java:114)
If after that I'll try to open same dataSpec through the Cache, it will be blocked here.
I think that CacheWriter must close datasources when any error occur, not only IOException.
