Add read cooldown to allow card removal in Chameleon module

[bruno-1337]

Proposed Changes

Added a 2-second cooldown period after successful card reads in Chameleon module to prevent immediate re-reading. This gives users time to remove the card from the Chameleon Ultra device before subsequent read attempts.

Types of Changes

• Bugfix (addresses unintended immediate re-read behavior)
• Hardware interaction improvement

The same bug happens when reading tags using the module boards like RFID2 and pn532. You could apply the same fix to the TagOMatic::read_card() method in the tag_o_matic.cpp file.

you were supposed to keep the chameleon code as well as it’s a different application. Same fix in both places
