- Ensure there is enough disk space for the write file
- Switch streaming mode only if necessary
- Return `Err` on seeking errors, instead of exiting
- Use the actual position after seeking
This change fixes two issues with the error handling of the
Symphonia decode loop.
1) `Error::ResetRequired` should always be propagated to jump
to the next Spotify track.
2) On a decode error, get a new packet and try again instead of
propagating the error and jumping to the next track.
- Configure the decoder according to Spotify's metadata, don't probe
- Return from `AudioFile::open` as soon as possible, with the smallest
possible block size suitable for opening the decoder, so the UI
transitions from loading to playing/paused state. From there,
the regular prefetching will take over.
- Set ideal sample buffer size after decoding first full packet
- Prevent audio glitches after seeking
- Reset decoder when the format reader requires it

- Switch from `lewton` to `Symphonia`. This is a pure Rust demuxer
and decoder in active development that supports a wide range of
formats, including Ogg Vorbis, MP3, AAC and FLAC for future HiFi
support. At the moment only Ogg Vorbis and MP3 are enabled; all
AAC files are DRM-protected.
- Bump MSRV to 1.51, required for `Symphonia`.
- Filter out all files whose format is not specified.
- Not all episodes seem to be encrypted. If we can't get an audio
key, try and see if we can play the file without decryption.
- After seeking, report the actual position instead of the target.
- Remove the 0xa7 bytes offset from `Subfile`, `Symphonia` does
not balk at Spotify's custom Ogg packet before it. This also
simplifies handling of formats other than Ogg Vorbis.
- When there is no next track to load, signal the UI that the
player has stopped. Before, the player would get stuck in an
infinite reloading loop when there was only one track in the
queue and that track could not be loaded.
- Don't load explicit tracks when the client setting forbids them
- When a client switches explicit filtering on *while* playing
an explicit track, immediately skip to the next track
