Support for NFC NTAG203

[evilpete]

Flipper will scan NTAG215 but not the simular/simpler lesser memory NTAG203 tags

NTAG203 and the NTAG215 are from the same NTAG family of chips (Both Type 2) ( ECC signatures are not supported in the NTAG203)

I can take this on after #1313 is merged. Note that NTAG203 is quite different from NTAG21x from the lack of configuration area, and is not a simple extension of original Mifare Ultralight due to the in-array counters and odd dynamic lock bytes, so there's some effort required to emulate it properly.

Edit: there's no GET_VERSION support either, so this will have to be detected by attempting to read page 41 after GET_VERSION NAKs.

Ran into a little snag with this, I'm not sure where to source actual NTAG203s. The cards Adafruit sells are counterfeit NTAG213s.

want me to mail you a couple?? I've been looking into it, it seems they're obsolete yet at the same time they are still in use everywhere.

Currently asking Adafruit to confirm whether they have an inventory of any NTAG203s, but if they don't, then sure.

[GMMan]

Adafruit said their manufacturer switched chips on them, so their stock is not guaranteed to be NTAG203. I've sent you an email to the address you have on your commits.

[evilpete]

no problem I'll dig a few out and the other later today, direct email me the shipping address.

@gornekich what do you think? Can we include it in our plans?

[GMMan]

@evilpete Got the tags, and finished up the PR.
