Emulator files

Files the emulator entries need that are not downloadable as one file elsewhere.

xteink-x4pro-flash-7.6.8-emulator.bin: Xteink's official X4 Pro firmware 7.6.8 as a full 16 MB flash image, so eink-qemu can boot it:

• the 7.6.8 app: Xteink's factory firmware as served by crosspointreader.com (/api/firmware/stock?model=x4pro&lang=en), unchanged;
• the bootloader and partition table: from Xteink's own public full firmware package 7.4.4 (api-prod.xteink.cn, the one Xteink's web flasher uses);
• the app placed in the first app slot, the OTA data cleared. Nothing inside the firmware was changed.
  Xteink's firmware is closed source and belongs to Xteink; it is here only so the emulator can run it.
