feature request: hex input

[cdslashetc]

I've been looking for a CLI program to convert hex to z85 and this is the closest program that I have found. I suppose the difficulty would be validating input--or just crashing with ugly error if input is invalid. This could be useful for taking hash generated by some other program and just using hashrat to convert the format.

The problem is that hashrat internally feeds the input through a hashing routine. I'll write another program to do this conversion, I think you're right that there's not one out there.
