Add pn7150

[TheFilipcom4607]

Adds circuitpython-pn7150 as libraries/drivers/pn7150, pinned at the 1.4.0 tag, plus a line in circuitpython_community_library_list.md.

It is a driver for the NXP PN7150 NFC controller. It reads NTAG/Ultralight, Mifare Classic, DESFire/ISO-DEP, ISO15693 and FeliCa, decodes and writes NDEF, and can emulate a Type 4 tag so a phone tapped on the board opens a URL. Single file, MIT, and it imports only core modules (busio, digitalio, supervisor, micropython, time), so it has no dependencies to resolve.

There is currently no PN7150 or other NFC reader driver in the bundle, so this is not a duplicate of anything here.

I built the bundle locally with circuitpython-build-bundles using the same arguments as build.sh, and the library builds clean:

lib/pn7150.mpy                        29000 bytes
examples/pn7150/nfc_scanner.py
examples/pn7150/example_write_tag.py
examples/pn7150/badge_reader.py
examples/pn7150/emulate_ndef.py
examples/pn7150/reader_and_card.py
requirements/pn7150/{requirements.txt,pyproject.toml}

Version 1.4.0 is picked up from the tag and stamped into __version__. The repo already uses adafruit/workflows-circuitpython-libs/release-gh to attach bundle zips to each release, and declares [tool.setuptools] py-modules in pyproject.toml rather than relying on autodetection.

Development happens on hardware, an iLabs Challenger RP2040 NFC, and the readme lists which tag types and technologies have been verified there. I will keep up with build-tools changes if any of them affect the library.
