Feat: split a sample into two when resolving spirals

[pbeaucage]

Frequently, a spiral scan identifies two equally viable but distinct regions of interest. It would be nice if resolve_spirals could accept a comma-separated list of "good" points, which would be used to:

• copy.deepcopy the sample object to a new sample in the bar for each number
• set the matched location for each copy to the corresponding spiral search position
• Copy all acquisitions from the sample to its duplicate (may happen automatically)

Thanks to Lucas and Julia who came up with this idea.

a pull request for this would be welcome - it's been something I've wanted for a while

This is actually for the rsoxs reposition, not this one. This package does not include resolve_spirals. Can you open the issue there instead?
