undeclared dependency on pytest, new release requested

[hexylena]

Hey y'all, just installed the package via pip and saw an error due to pytest, I'd written a long issue about it before discovering e95b1ab so it's already been fixed, yay! Could a new release be made at some point in the future (no rush from my side.)

Agreed - have contacted @Logan-174 by email to gain access to the pypi entry.
