Implements proper server negotation for performing transcoding Depending on the user's platform (i.e. iOS, Android) and the desired quality specified in the settings, Jellify will playback a transcoded audio file from Jellyfin This is helpful when the source audio file is not compatible with the user's device (i.e. playing back an ALAC encoded .M4A on Android) or if the user want to stream at a lower quality to save bandwidth This also drives downloads in different qualities, meaning the download quality selector in the Settings is now working properly. When a track is downloaded, it will download at the quality selected by the user, and in a format compatible with the device There is also a toggle in the "Player" Settings for displaying a badge in the player that shows the quality and container of the audio being played
