add fixtures to parameterization

[kianorr]

resolves #1104

[kianorr]

Not sure if it's worth it to load each h5 file every time.

Also I left out nested_coils = MixedCoilSet(sym_coils, mixed_coils, check_intersection=False) and spline_coil = mixed_coils.coils[-1].copy() because I couldn't think of a clean way to incorporate them yet.

make the coilsets as conftest fixtures

[kianorr]

I added a nested coil set fixture so it's working now. But, I still need to decide on whether we should save the h5 file in the fixture or if we should just return the coil set.

[dpanici]

close when #1362 is merged in, I think

[YigitElma]

closing since #1362 solved this
