lsnes rr1 delta 1 is released. lsnes is SNES rerecording emulator based on bsnes core.

lsnes rr1-Δ1 Changelog:
- Raw audio/video dump
- Fix unattended dumping
- Build the win32 build with compat core instead of accuracy.

Using compat core instead of accuracy gives about 2x speed and should only affect Air Strike Patrol (which uses graphics effects Compat can't emulate).
