old bitarray version compatibility issue

[fiene-weber]

the method bitarr.endian() used in line 41 in in utils/utils.py is not supported anymore since bitarray==1.8.x. could be replaced by something self-built like endian = getattr(bitarr, 'endian', 'big') if hasattr(bitarr, 'endian') else 'big'

Could you try to install from git (pip install git+https://github.com/SiLab-Bonn/basil) and see if it works for you?

It was fixed in 09870e2, but we are struggling to make a new Pypi release at the moment, unfortunately.
