feat: create Microscope (model) from summary metadata

[tlambert03]

This PR follows on #358 and allows creating an instance of pymmcore_plus.model.Microscope from a SummaryMetaV1 dict, with pymmcore_plus.model.Microscope.from_summary_metadata As a reminder, the Microscope object is mostly used as a runtime representation of a non-loaded Core. It's used to create config files, and is used by the pymmcore-widgets ConfigWizard. So, with this PR, it would be straightforward to load the full state of the core as used in a previous experiment
