feat(python): add handler for python PEPs

[reegnz]

python peps are enhancement proposal documents, they are usually
referred to as PEP-xxx, PEP xxx or PEPxxx, the handler handles each of
those cases.

I'll add some tests to this PR a bit later, just wanted to feel around if this would be a good candidate for this plugin.

[chrishrb]

can you also add some tests here?

[reegnz]

Thanks for pinging, I totally forgot about this PR! 😅

Added a test.

[chrishrb]

you also have to add the handler in the handler.lua file. here is also the priority set, so it makes sense to add it above or below the cve_handler?

[reegnz]

Whoops, turns out as I was testing it I had it as a custom handler so I didn't notice it not getting registered.
Added the handler registering code now.
Maybe some integration test would catch that.
eg. not directly loading the handler code in tests but rather loading the entire plugin, exercising the gx mapping and capturing the output with an open_callback, and also make the open_browser_app a NOOP during testing.

I can see if I can improve that when I have some time, what do you think @chrishrb?

Strictly in a follow-up PR 😅

[chrishrb]

yes, of course. that would be super cool, tests are always welcome (and super important!) 👍
