fix: move and document the signature helpers

[grantseltzer]

This moves both the rego and go helper functions into their own package, updates usage and Makefile accordingly. (#599)

It also adds notes in the README about them (#538).

I do think the rego helpers should move to a dedicated package (like you already did before) (just the name, not the directory). in rego conventions that would be like package tracee.helpers

also, probably worth adding code comments to document the helper functions themselves. but this can be a separate PR if you'd like
