music: refactor music grouping
Completely refactor the way music is grouped up into artists and albums. The issue with previous attempts at implementing better artist management was the reliance on MediaStore IDs in many parts of the program. Dumpster this by merging the hash and ID values into a single field that is garunteed to be unique enough. This allows songs to be adequately grouped into case-insensitive artists while also deduplicating albums that may have been split my MediaStore due to heterogeneous formats. Resolves #66.

while `ActionHeader` corresponds to an action with a dedicated icon, such as with sorting.
|

|
||||
Other data types represent a specific UI configuration or state:
|
||||
|
||||
- Sealed classes like `Sort` and `HeaderString` contain data with them that can be modified.
|
||||
- Enums like `DisplayMode` and `LoopMode` only contain static data, such as a string resource.
|
||||
|
||||
Things to keep in mind while working with music data:
|
||||
- `id` is not derived from the `MediaStore` ID of the music data. It is actually a hash of the unique fields of the music data.
|
||||
Attempting to use it as a `MediaStore` ID will result in errors.
|
||||
- Any field beginning with `_mediaStore` is off-limits. These fields are meant for use within MusicLoader and generally provide
|
||||
poor UX to the user.
|
||||
- Generally, `name` is used when saving music data to storage, while `resolvedName` is used when displaying music data to the user.
|
||||
- For `Song` instances in particular, prefer `resolvedAlbumName` and `resolvedArtistName` over `album.resolvedName` and `album.artist.resolvedName`
|
||||
- For `Album` instances in particular, prefer `resolvedArtistName` over `artist.resolvedName`
|

#### Music Access
|
||||
|
||||
All music on a system is asynchronously loaded into the shared object `MusicStore`. Because of this, **`MusicStore` may not be available at all times**.
