Any way to add CAST_XMR?   There are no good programs to mine XMR with.  XMR-Stak running 1 thread instead of 2 is about 15% slower than cast.    Im assuming it must be a challenge in implement Cast or else it would have been done already.  My RX580s get 925 h/s on Cast, and only 750 on xmr stak with 1 thread.  Multiply that by 13 and I'm looking at a Vega amount of hashrate I am losing.

Peace
