Pin functionality for QFN-80 package

[thelenlucas]

The QFN-80 package (RP2350B/RP2354B) has an additional series of GPIO pins GPIO30-GPIO47. These pins currently exist as type-level variants, but do not have functionality implemented beyond FunctionSIO<C>. In theory, this should be fairly straightforward to implement, because these pins do not introduce any new peripherals in and of themselves, but I don't have any experience in HAL development, and don't know this would be effected.

As an aside, are there any good resources floating around on learning HAL development or "raw" embedded Rust? I'd love to be able to contribute, especially coming from a C/C++ background the macros that seem to impliment the ValidFunction traits seem very arcane.

https://github.com/rust-embedded/awesome-embedded-rust contains a lot of links to learning resources and crates for embedded devices.
