SublimeLinter 4 support/compatibility

[XenHat]

The package currently does not work with SublimeLinter 4 due to API changes.
Until I find a way to preserve functionality of this plugin, SublimeLinter 3 is the only option.

Turning off automatic package upgrade is not a solution that pleases me but I do not currently have the knowledge/time to re-write the plugin in a way that makes SL4 happy.

@XenHat I can send you a pull request for SL4 as well as ST4.

mcpp isn't supported on macOS 12 (Monterey) or 13 (Ventura). So maybe we can drop preprocessor support there?

@Sei-Lisa do you know of any workarounds for mcpp support on newer macOSes?

@buildersbrewery clang's cpp is another preprocessor. I hear it's installed with xcode.

[XenHat]

Sure!

I haven't looked into clang as a preprocessor for this, but I like clang a lot so this is fine by me.
