Process recorded file using Spotify playlist

[a-rich]

Is your feature request related to a problem? Please describe.
Splitting a recorded audio file into tracks is time consuming and error prone. Mistypes in the file names affect downstream processes like deriving title and artist tags and create similarity search issues when using features like CHECK_TRACKS. Title, artist, and other tags can automatically be exported with tracks using data from the Spotify API.

Describe the solution you'd like
Given a RECORDING_FILE and a RECORDING_PLAYLIST, split a file into individual tracks, name the files using the title and artist from the Spotify API, normalize the amplitude using NORMALIZE_AUDIO_HEADROOM, and then export in the desired AUDIO_FORMAT and AUDIO_BITRATE with tags.
