There's incorrect documentation about a few options here, which confused me until I realized it didn't line up with what's in the source. This PR fixes them up. Namely:
The manpage documents the --classic flag for using the classic mixers, and implies there might be non-Amiga options. The actual option is named --amiga and is Amiga-specific.
The manpage and README both document a keyboard option to change the mixer at runtime, but that option doesn't seem to exist.
