"""
Take a binary file as input and prints its bytes as ordinals, formatted as an
array. The goal is to take a file that has caused a crash during binary fuzzing
and convert it into a unit test that can detect panic regressioins.
See darkfi/src/zkas/decoder.rs for example unit tests.

input:
    - binary.bin

output
    - [1, 2, 3, 5, 8, 11]

Now the output can be easily pasted into a unit test.
