sameboy: update to 0.15.8

                                    Changes

Version 0.15.8

   This version is backwards compatible with save states from SameBoy 0.14.3
   and newer, as well as save states from any BESS compliant emulator

  New/Improved Features

     * The button mapped to B, on both the keyboard and controllers, can now
       be used to return from menus in the SDL frontend

Version 0.15.7

   This version is backwards compatible with save states from SameBoy 0.14.3
   and newer, as well as save states from any BESS compliant emulator

  New/Improved Features

     * The debugger now has an interrupt command, in addition to the
       previously-available ^C key sequence
     * The lcd command now displays the background shifter and fetcher states
     * The tick debugger command now has an optional keep argument, which
       prevents resetting the tick count

  Accuracy Improvements/Fixes

     * Fixed a regression that made DMA restart timing inaccurate
     * Fixed a regression that caused ROMs that trigger one of the pixel
       insertion glitches to display incorrectly (Release builds) or trigger
       an assertion (Debug builds)
     * Fixed a different regression in a different pixel insertion glitch

  Bug Fixes

     * Fixed a bug where the debugger finish command did not behave as
       expected in certain cases where the ROM manipulated the stack

       RGBDS 0.4.x has been dropped
     * Fixed potential compilation warnings for incoming versions of Clang
       and GCC
     * Added the GB_quick_reset API

       core
     * The debugger now guides users to use the help command
     * Both frontends can now selectively mute and unmute each of the 4 audio
       channels

       speed after switching models
