Please document/build a process to quickly locally test when adding a new tool

[skyf0l]

All in title: it's hell to test the installation of a new tool locally, because it takes too long to build. I think it would be interesting to have a quick process for testing in local.

Example: I can run something like fast_run.sh install_rsacracker locally. Under the hood, it will pull a base image and only run this command, and then run tests. Alternatively, if I have a lot of disk space, I could run fast_run.sh --all install_rsacracker, which would do the same thing but on all images (base, web, osint, full, etc.).

Okay, it's possible that another step will break the installation, but it's already better than waiting for a CI :)
