contrib: LF Programming script

Submitting a well documented Lua script whose purpose is to do
bulk, repeated, sequential programming of RFID tags.  Could be useful
for users of the ACCX Open Access 4.0 or other simple RFID systems.

Tags programmed with this would potentially be vulnerabile to bisection
attacks, etc... But honestly, they likely would have been anyway.

To use run from within the proxmark3 client:

```
proxmark3> script run lf_bulk_program.lua  -b 1000 -c 5 -f 23
--- Executing: lf_bulk_program.lua, args '-b 1000 -c 5 -f 23'
Press enter to program card 1000:23 (hex: 0020042e07d1)
