Pip install error involving numpy

[LinearParadox]

Not an expert in installation of pip packages, so not sure how this could be fixed:

but it seems that fseq2 requires numpy during buildtime, which to my understanding is isolated from the runtime virtual environment. This causes a package not found install error. You can get around this using the --no-build-isolation flag in pip, but this requires a relatively new version of pip, and to my understanding is anti-pattern. Is there a way to add the numpy dependency to the build requirements?

@aboyle Just wanted to add that #20 resolves this issue and if merged would close.
