Turn LoROM ROM reads back on in RetroArch

[strotlog]

LoROM games such as Super Metroid previously had an issue reading any part of the ROM, other than the first 1%, when using RetroArch's READ_CORE_MEMORY API.

This issue is now fixed in RetroArch 1.10.1 and newer: libretro/RetroArch#13664

So QUsb2Snes should now be able to provide LoROM ROM data over the websocket when the game is running in RetroArch.

Thank for precising the version. Ra stuff is a mess
