Device XPU - output format

[SamGG]

Hi,
Yep, great project. Thanks to @AyedaOk to point it.

1. I installed torch for XPU (Intel) and added xpu as a device in RawfForge code. This works like a charm for RW2 from Panasonic LX15/LX10.
   If you could update the code for people working on laptop. This should work also with RawRefinery, but I didn't try.
2. While the RAW file is read perfectly, the output file does not keep all information (for the photo I tested). The lens correction should be selected manually (I am using ART). Could you tell more about the demosaicing and chromatic aberration correction?
   PS: change the README title.
   Best.
