Rewrite Diamond for efficiency

[Snaacky]

The current version of Diamond is rather unoptimized and endlessly eats CPU cycles. A much simpler way to achieve the same effect would be to pattern scan for the glow update and write a JMP/NOP operation so we can replace the infinite while loop.

It's been nearly a year since the last update of Diamond so I'm not sure when (if ever) that I'll get around to this. It would be nice to receive a PR for this as it's very easily achievable using Pymem.
