Indigo optimisation for Apple M1 / M1 pro / M1 max

[mpro31]

Hi guys, I hope you're doing well.
Just wanted to ask if you're planning a M1 compatible version.
Since Apple has released a super fast new chip with up to 4x the GPU speed of 5600m and CPU speeds equal to a 12core xeon, I guess Indigo could run amazing if optimised.

Hi.
Most important is that Indigo could adhere to Metal API for GPU computing, since OpenCL is deprecated on Mac environment.

Ciao!
