[Feat] replace `fast-deep-equal` with `fast-equals`

[mrienstra]

Target Use Case

Replace the unmaintained (2020) and non-ESM fast-deep-equal with fast-equals, as @googlemaps/markerclusterer did recently, see googlemaps/js-markerclusterer#610 and googlemaps/js-markerclusterer#893.

Proposal

Current usage of fast-deep-equal is in src/libraries/use-deep-compare-effect.tsx.

Looks like changes would be:

- import isDeepEqual from 'fast-deep-equal';
+ import { deepEqual } from 'fast-equals';

... and:

- !isDeepEqual(deps, ref.current)
+ !deepEqual(deps, ref.current)

[usefulthink]

I'm open to making this change, with a tendency towards inlining a simple implementation of what we actually need into our library to avoid external dependencies altogether.

But to clarify, are there any actual problems with the way it is at the moment?

Re: actual problems: Not that I'm aware of. Presumably one could be affected by a bug, e.g. epoberezkin/fast-deep-equal#111, but that's just a hypothetical.
