WIP: Refactor NFC

[nickray]

WIP / do not merge, however feedback is welcome!

Several goals:

• rename the iso14443 library to nfc-device, bringing it in closer analogy with usb-device.
• this then turns fm11nc08 into something analogous to a UsbBus implementation
• remove dependency of fm11nc08 on lpc55-hal
• de-C the FM11NC08 driver, adding more types (using bitflags library as elsewhere), using more Rust combinators, using closures to DRY up, etc.
• define the contact/contactless interchanges in iso7816 itself (not optimal, but better than in apdu-dispatch, IMO) to avoid a dependency of usbd-ccid and nfc-device on apdu-dispatch, which is more opinionated and particular to us
• fix minor regressions

Out of scope is a closer re-union of apdu-dispatch and [ctap]hid-dispatch.
