[Feature Request] Add Mangabaka as metadata source

[hstraten]

Is your feature request related to a problem? Please describe.
No

Describe the solution you'd like
Add https://mangabaka.dev/ as datasource, it adds metadata from multiple sources (Anilist, MyAnimelist, MangaUpdates, etc.) into one source
Offline database, online API or both would be awesome.

Describe alternatives you've considered
Currently copy/pasting manually after updating from either MangaUpdate or Anilist (mainly tags and genres)

Additional context
Add mangabaka to this metasource dropdown
