Refactor `cast wallet vanity` to compute via GPU

[wildmolasses]

Component

Cast

Describe the feature you would like

Profanity is now unsafe and archived; a maintained vanity address generator that uses GPU would be useful. Thank you!

Additional context

No response

• would also be cool to be able to grind salts for vanity create2 contract addresses a la https://github.com/0age/create2crunch

Would note here that we can't lock into GPU only since some people use Cast on servers w/o GPUs

[mattsse]

yeah this would need to be an entirely separate thing.

definitely out of scope for cast itself, also as we've seen with profanity, there can be additional issues when it comes to randomness so I wouldn't feel confident shipping something like this without proper security assessments.

Update, Profanity was forked by 1inch and is now maintained as Profanity2: https://github.com/1inch/profanity2

Marking this an not planned as GPU functionality is not planned
