Added a utility script to convert a 'dumpdata.bin'-file into the 'eml'-format that the emulator uses. Did not find any built-in way to do this, perhaps such functionality already exists.. ?

This script takes a dumpfile from 'hf mf dump' and converts it to a format that can be used
|
||||||
|
by the emulator

|
||||||
|
Arguments:
|
||||||
|
-h This help
|
||||||
|
-i <file> Specifies the dump-file (input). If omitted, 'dumpdata.bin' is used
|
||||||
|
-o <filename> Speciies the output file. If omitted, <uid>.eml is used.

In the future, we may implement so that scripts are invoked directly

into a 'main' function, instead of being executed blindly. For future
