fix: resolve the DSP ROMs as a pair the code takes

Dolphin and its forks hash dsp_rom.bin and dsp_coef.bin together and
warn on any combination outside known_roms. The profiles now carry the
accepted pairs, and the resolver keeps both files inside the first pair
the collection holds whole: MMJR and Ishiiruka were served the free ROM
beside the official coefficients.
