Kodi integration for bsnes-mercury balanced core

 This package contains the appropriate Kodi configuration to allow the use of
 the bsnes-mercury balanced libretro core with Kodi via kodi-game-libretro.
 .
 This core is enabled to emulate only SNES hardware and its subsystems (from
 the command line only), like Super Game Boy, Satellaview and Sufami Turbo.
 .
 bsnes-mercury is a fork of higan, aiming to restore some useful features that
 have been removed, as well as improving performance a bit. Maximum accuracy is
 still uncompromisable; anything that affects accuracy is optional and off by
 default. The name is because metals are shiny, like the accuracy promises of
 bsnes, and mercury is the fastest metal.
 .
 This package pulls in the bsnes-mercury balanced core, which tries to keep a
 good balance between accuracy and performance. It runs almost all SNES games.
