added support for 7 byte uid

[dsl400]

a quick hack to read the 7 byte UID

documentation:
page 4 describes how it works
https://www.nxp.com/docs/en/application-note/AN10927.pdf
page 32 contains the instruction set bytecodes

hey @dsl400 thx for your work, i appreciate your contribution.

a suggestions to your code base:
From my knowledge i think you should use "let" only if you want to re-assign new values to a variable after its declaration.
I think in most cases you can use "const".

some variables where you really need "let" => "select", "uidCheck"

Hi @dsl400 , I have implemented the changes and it does not currently work for a MIFARE DESFire EV2 which is also a 7 byte UID. Was this code working for you with other NFCs with 7 byte UIDs? Was this change "complete"?
Thanks

I have no Ideea if it works with MIFARE DESFire EV2, you will have to consult the documentation and see if it needs any changes, just like I did
