Metal GPU support not working

[lukechilds]

Awesome work!

Is this supposed to work on metal? On my M4 Max MacBook Pro the GPU is not detected

$ cargo run --release generate --no-tui --pattern 1Test

Also just fyi taproot address format also doesn't seem to be working

$ cargo run --release generate --no-tui --pattern ^bc1pluke --format p2tr
    Finished `release` profile [optimized] target(s) in 0.06s
     Running `target/release/vgen generate --no-tui --pattern '^bc1pluke' --format p2tr`
error: invalid value 'p2tr' for '--format <FORMAT>'
  [possible values: p2pkh, p2wpkh, ethereum]

For more information, try '--help'.

Thanks for reporting. I don't have a Mac, so it's hard for me to test it. I was basing it on theory, and in theory it should work, but as you can see, in practice something isn't right. I'll release the fixes you reported within the next 1-2 days and ask you to test it.

Awesome, thanks @oritwoen!

@lukechilds can you check on the main branch and the latest commit if the error still occurs before I create a release?

[lukechilds]

@oritwoen I'm getting this
