service: bcat: Remove BoxCat BCAT implementation 

The current implementation of BoxCat as it stands is non-functional due to the reliance on a server providing BCAT files.
This implementation will eventually be replaced with one that allows the use of local BCAT files dumped from a Nintendo Switch.
