Support For Ascii Hex

[Alexander Hanel]

Discussion/Issue a user had https://www.openrce.org/forums/posts/2200#4753 Need to add support for ascii hex to bin. Simple for loop reading two bytes at a time and adding blank chars for error. Use binascii.a2b_hex(data). Will also need to add command line argument parsing.
