Add support to .WIA and .RVZ game files

[Bobsican]

They're more modern (And effectively standard nowadays) game file formats offered by Dolphin that are pending support for bisecting purposes.

I had no idea that people still used this tool, especially since I think I told JMC and the gang to unpin it because I wasn't really involved in emudev anymore

This is trivial to implement (Just tweaking a single line of code), but I'm at a tech conference until tomorrow.

I'll set an alarm to implement this and compile a new build this weekend.

Ideally it probably should also disable the finding of such formats for versions of Dolphin earlier than 5.0-12188, as versions earlier than that don't support them.

[Helios747]

The bisecter seems to have several problems now due to infra and probably other changes that makes this tool largely useless.

Because I'm not involved in emudev anymore I'm not really interested in fixing this. Anybody reading is free to fork this and fix it as needed.
