Replace lodash dependency with lodash.isEmpty

[davidjoy]

Currently the Studio footer depends on the entire lodash library. This pulls in significantly more code than we need, as we only use the isEmpty function.

We should replace the lodash dependency with the lodash.isEmpty library; this will take a decently sized chunk out of the bundle sizes of our MFEs.

[regisb]

I ran npx howfat . in this repo and this is what I got. If I'm reading this right, removing lodash is going to remove 1054 files (!!!) and 1.35 MB?
