Generic 4col/6col SANS data loader

[pbeaucage]

Need a generic text loader for SANS data, relies on having a robust filename to metadata loader class (issue #30)

also, having a way to digest header data in various forms (one line per entry, comma separated equals, Igor a:b;c:d etc)

[pbeaucage]

This could also be good for pre-reduced RSoXS data processed with Nika or the @EliotGann branch of Nika

What would it look like?

I actually have the stub of something I wrote for Camille - but basically have Igor export the circular and 0,90,180,270 sectors and then load those 4 into an xarray.

The benefit would be that you could do downline plotting, fitting, and comparison with pyhyper but still use the Nika reduction if you trust that more.

Ooh, ok I was thinking the opposite way.
