[FEAT] Imviz: Ability to remove or replace data sets

[hcferguson]

Description

It would be nice to have an easy way remove (or replace) a data set. Ideally,

Additional context

It was unclear to me from the documentation (and introspecting Imviz and Imviz.app) how to remove (or replace) a data set.

From Slack conversation @kecnry:

we didn’t expose this for data entries because of concerns with removing the reference data. In theory, we could loosen this restriction a bit to allow removing all but the last entry or something like that. There also isn’t a user-friendly exposed API, but you there are still ways to do it using deeper methods (imviz.app.data_collection.remove(imviz.app.data_collection[label]) or imviz.app.vue_data_item_remove({'item_name': label})).

In my normal workflow, I'm doing a lot of trial and error, so being able to remove or replace images from the collection would help to avoid it getting too confusing.

Note that this applies across all configs (except maybe mosviz) - see https://stsci.slack.com/archives/C232KCAFR/p1680028666129639].  The complication is how to handle “reference data” in glue, especially if there are outputs from plugins that have been added since.
