onig/onig_sys extremely outdated in Cargo deps

[DomT4]

Hi there,

I notice amp is using quite an outdated version of onig and onig_sys, 3.2.2 and 68.0.1 respectively from ~2018, when the current versions are 6.1.1 & 69.6.0. onig_sys in particular prior to version 4.0.0 needed cmake to compile, which can be problematic on macOS platforms running Apple Silicon. The cc crate also needs updating for full Apple Silicon support.

I was wondering if you'd be willing to update the Cargo dependencies so that Homebrew can package amp successfully on ARM macOS without having to manage the dependencies ourselves.

Thanks!
