update process data to pre-calculate prior information for some metrics

[ghar1821]

Some metrics, require information from unintegrated data, which does not change regardless of what methods the metrics were run on. So this needs to be calculated just once when the unintegrated data was created from common_dataset.h5ad file.

Go through each metric that require this calculation, like ratio of consistent peaks and functional marker preservation, and add whatever is needed from unintegrated into the uns.

May not do, because it is a big change. Will see.
