chore(deps): replace fast-deep-equal with fast-equals (#983)

fast-deep-equal hasn't been updated since 2020 and ships only CJS.
fast-equals is actively maintained, ships ESM + CJS, and is API-
compatible at the call site: deepEqual(a, b) takes the same arguments
and returns the same boolean.

Swap the dependency in package.json (fast-deep-equal ^3.1.3 ->
fast-equals ^5.0.0) and update every src/ import. The local binding
stays isDeepEqual via the rename-on-import form, so every call site is
unchanged. @googlemaps/markerclusterer made the same swap recently
(googlemaps/js-markerclusterer#893).

Closes #755
