feat(frontend): add package coloring for rust

[eh-am]

Closes #789

This PR contains 2 parts:

Some prep work, adding tests for existing coloring integrations

Couldn't add much tests for phpspy since our example is too simple.
Plus simplified the default one, since it seems to use go scheme by default.

Supports rust

For that the regex used is to just get whatever is before the first ::.

It's a bit naive, since it doesn't deal with cases such as

<core::future::from_generator::GenFuture<T> as core::future::future::Future>::poll

That @omarabid said it should be treated as core::future::future::Future::poll.

But should be a good start.
