VAG: Evolution Games variant + misc

[EdnessP]

• Add Evolution Games VAG variant [Rocket Power: Beach Bandits (PS2)]
• Add .RSM extension to DSP [Bully: Scholarship Edition (Wii)]
• Hide/Show SCREAM/XACT bank names if they match the input filename (like with RWS/AWD)
• Use intended AWD codec enum names

For enums where order matters (map 1:1 to some read int) I recommend adding the expected value: typedef enum { VAG = 0x00, PCM = 0x01, ... }. This makes them less brittle if moved around by mistake, and contrasts with other metas where enums are just helpers, plus you can simplify/remove the comment too.

Done. Also spotted a separate bug in XWB where the stream name wasn't being null terminated on all get_name fail cases, causing garbage to appear in the output stream name on XWBs that just have a valid bank name.

Some rare early XWBs also seem to hang/infinitely loop(?) even on the current public build, but I haven't looked at that yet.
Might also be a false positive, unsure. Nevermind, it was actually just be taking a reeeeeally long time to parse some XSBs.
