Add tag filters to LabelMap

[misaugstad]

Brief description of problem/feature

We can already filter by label type on LabelMap, but maybe it would be nice to filter by tag as well? 👀 We already want to do a redesign of the filtering legend (#2849), partially because of how large and unruly it's become. We'd really have to think about how to redo the legend to work with so many different filtering options, but it would be really cool to include!

Here's a look at what LabelMap with it's legend looks like now.
