upgrading 'hf mfu' (#830)

* chg: write new dump file format by @mceloff
* chg: rename 'hf mfu dump' option 'n' to 'f' to align with other commands and RRG repo
* chg: replace ISO14443A_CMD_READBLOCK by MIFARE_CMD_READBLOCK, same for WRITEBLOCK
* fix: mifare_ultra_readblock() returned 14 bytes instead of 16
* chg: param_gethex_ex() now checks maximum output buffer length
* chg: ul_comp_write() was incomplete and for magic testing only
* fix: 16bit ULC counter had been displayed as 32bit
* chg: add check for 7 Byte UID, drop check for ATQA in type identification GetHF14AMfU_Type()
* fix: send HALT instead of dropping field in order to maintain a defined state
* chg: DropField() when command ends
* chg: check for invalid page ranges in 'hf mfu dump'
* fix: print correct lock bits when page range is used
* fix: do not write (incomplete) dumpfile when page range is used
* add: use UID for filename when no filename is given (RRG repo)
* chg: don't clear trace on each ULC authentication, clear trace at beginning of each command
* fix: don't send (DESFire?) deselect command after authentication
