Experiment INI format allow for linspace specifications

[ksunden]

Currently I think we can support either independent numbers or fully specified lists

Enabling linspace specs would make saving experimental parameters as an INI a good way to hold and document common settings. Something like a tuple of (-500, 500, 64) would get translated to np.linspace(-500, 500, 64) rather than the three independent values

I would want a way to give fully specified values as well.

Would also be nice to have an export method which supported such syntax.

may actually be something that stems from tidy_headers parsing
