fp16 support

[zqOuO]

Hi,
thank you for this excellent repo. Is there any future work planned for bfp16 data type support for ptwt?

There have been a few requests in this direction recently. I hope to make time for this feature in early January.

Hi, fellow.
I would like to know the current development progress regarding fp16 support? And with fp16, does it mean it can run on MPS?
