Added a feature of Reading the ID of the NFC Card only with param of "id"

[adelcsc]

Current termux-nfc api allows to read/write the content of NFEF types only.

I had a case where i needed to read the NFC Chip ID of a non-NFEF card which of course the api returned an error of "we only support NFEF card", so i added a feature of reading only the id of chip using the parameter "id", example :

termux-nfc -r id

this returns a result of :

{
  "card_id":"XXXXX"
}
