This is a script to communicate with a CALYSPO / 14443b tag using the '14b raw' commands

Arguments:
	-b 				123
Examples : 
	script run f -b 11223344
	script run f

Examples : 

# 1. Connect and don't disconnect
script run f  
# 2. Send mf auth, read response
script run f
# 3. disconnect
script run f
