Errors when using ihex_rs_from_file()

[rwhitworth]

Hello,
I was using American Fuzzy Lop (afl-fuzz) to fuzz input to a modified version of test program that calls ihex_rs_from_file(argv[1]) and found these input files cause the program to exit unexpectedly.
Is fixing these crashes something you're interested in? The input files can be found here: https://github.com/rwhitworth/libcintelhex-fuzz.

Let me know if I can provide any more information to help narrow down this issue.
