Updating Syntax of Magnetics and Summary ids'

[LariDG]

Using the IMAS_MASTU mappings to update the magnetics and summary mappings here.

Probably shouldn't be a blocker now but for info for the summary ids.

One of the rules here is that summary should present reduced datasets compared to other ones. Concretely that there should be a common timebase with a small number of points (100-300 I think) and all signal data in summary needs to be interpolated onto that common timebase. What we have now is just the raw signals so the imas-python package will refuse to write to ids with strict checking as it breaks the homogeneous_time rule.

The reason this shouldn't be blocking now is that the interpolation functionality isn't available in libtokamap yet so there's practically not much you can do except maybe tag the relevant ones with a comment that interpolation transform will need to be added later. guess it's a bit like the geometry ones where you've got the skeleton in place even though the backend functionality isn't there yet.
