Generalise `fastf1` proxy

[psychemedia]

The fastf1 CORS proxy was generated using a prompt to claude.ai and inspired by the monkey patching trick used by requests-cache to patch requests and add cacheing abilities to it without having ro fork the requests package itself.

The code included the fastf1_proxy is currently tied in to fastf1 but could presumably be simplified to produce:

• a package that can add a proxy to requests in the absence of requests-cache;
• a package that can add a proxy to requests in the presence of requests-cache.

Also, the fastf1 package could be iterated to use the fastf1 logger, and then either added as a monkey patch package to fastf1 or integrated more deeply within the fastf1 requests machinery.

I suspect that the fastf1 live timing requests don't work in their current form in emscripten environments, but if they did, would they need proxying too?
