Tim Allen d87a0f633d Update to bsnes v107r4 beta release.
byuu says:

  - bsnes: added video filters from bsnes v082
  - bsnes: added ZSNES snow effect option when games paused or unloaded
    (no, I'm not joking)
  - bsnes: added 7-zip support (LZMA 19.00 SDK)

[Recent higan WIPs have also mentioned bsnes changes, although the higan code
no longer includes the bsnes code. These changes include:

  - higan, bsnes: added EXLOROM, EXLOROM-RAM, EXHIROM mappings
  - higan, bsnes: focus the viewport after leaving fullscreen exclusive
    mode
  - bsnes: re-added mightymo's cheat code database
  - bsnes: improved make install rules for the game and cheat code
    databases
  - bsnes: delayed construction of hiro::Window objects to properly show
    bsnes window icons
