FIX: a solution for the issue "hf mf esave - always saves 4K"
FIX: a solution for the issue "hf eload, esave, cload, save - filepath variable too short" CHG: minor code clean up. ADD: AES / CRC16 for lua. (and tnp3xx scripts.) ADD: tnp3dump.lua script to dump tnp3xx tags. ADD: tnp3sim.lua script to let PM3 imitate an tnp3xx tag. Needs to be tested live
