Regex hint processor

[Bernardstanislas]

Regex hint processer

Description

Linked to #523.

Implements a RegexHintProcessor, which only holds custom hints. The hints match the code based on a regex.

This processor does not have any builtin, using it can be done in conjonction with the BuiltinHintProcessor with a composite pattern for example. This is left to the user project of the vm.

I would suggest this is better implemented as part of a downstream project.
Regardless of that, I strongly suggest to move the regex compilation to the hint compilation step, as it tends to be a major performance bottleneck.

Oh I see, I'll add it to our repo then.

Thanks for the feedback, agreed with the regex compilation remark :)
