Cells read from swc files cannot be pickled

[michaeldeistler]

import jaxley as jx
import pickle

cell = jx.read_swc("tests/swc_files/morph_250.swc", ncomp=2)

with open("test.pkl", "wb") as handle:
    pickle.dump(cell, handle)

This must be because I made the _radius_generating_fn an attribute of cell, such that one can post-hoc run set_ncomp().

A super quick fix (that does no longer allow calling set_ncomp() is to do:

cell = jx.read_swc("../../tests/swc_files/morph_250.swc", ncomp=2)
cell._radius_generating_fns = None

with open("test.pkl", "wb") as handle:
    pickle.dump(cell, handle)

oh damn. This should have been caught by tests/test_pickle. We should add another test_case here.

Can also make use the fixtures in conftest.py.
