Describe the bug
Both version and signature in NTAG 21X can't be written in magic gen4 cards since they are stored in blocks 242-251, which unless you allow writing in them, it will yield a write error.
To Reproduce
Steps to reproduce the behavior:
With a magic card gen4 aka "ultimate card", try changing the version or signature using commands like:
script run hf_mf_ultimatecard -v 0004040201000f03
script run hf_mf_ultimatecard -s 8B76052EE42F5567BEB53238B3E3F9950707C0DCC956B5C5EFCFDB709B2D82B3
script run hf_mf_ultimatecard -w 1
When reaching those "problematic" blocks, it fails with wrote block ..XX failed
Expected behavior
It should properly write in those blocks, therefore setting version and signature.

Screenshots N/A
Desktop (please complete the following information): N/A (using latest available version of the script, see https://github.com/RfidResearchGroup/proxmark3/blob/v4.18218/client/luascripts/hf_mf_ultimatecard.lua)
Additional context I'll be sending a PR fixing it shortly.
