Jennifer Wilcox eaea9ae1ed Concentrate the unsafe register constructs 
This moves almost all of the unsafe stuff together. The last remaining bit is going to need a PAC fix.

Jennifer Wilcox 8290368c10 Pull pads out of reset and wait 
We're technically supposed to wait for these resets to finish before poking at registers. This seems to fix the instability I was seeing on the input example especially (TBH I have no idea how it ever worked)

Jennifer Wilcox 2c3a0956fa Add input support, examples, SIO/PADS ownership 
Sorry this is a large commit :(

This adds support for input pins, including pulling them high or low.

It also adds two examples: the start of a classic blinky LED example, and an example for reading input.

Jan Niehusmann d6231bd3ec fix rom_table_lookup 
It seems like the rom_table_lookup missed one level of
pointer dereferencing.

After comparing it to the working call to reset_usb_boot() in
https://github.com/jannic/rp-microcontroller-rs/blob/master/util/rp2040-panic-usb-boot/src/lib.rs,
I changed the code until it generated basically the same assembly.

With that change, I was able to successfully call rom_data::reset_to_usb_boot()

I still don't like the type RomTableLookupFn, which just returns
some generic T without any checks, and I think rom_table_lookup
should be unsafe. But as none of those are pub, it doesn't matter too
much. So I just made the changes necessary to make the code work.
