feat: coalescing calls + feature: max cache size (#877)

* feature: coalescing calls

If options.coalesce is set, multiple calls to the circuitbreaker will
be handled as one, within the given timeframe (options.coalesceTTL).

feature: max cache size

To prevent internal cache from growing without bounds (and triggering
OOM crashes), the cache is now limited to 2^24 items. This is an insane
amount, so options.cacheSize and options.coalesceSize have been added
to control this.

* PR feedback: remove cache.delete function
