Updatable rates

UPDATE_RATE will replace the rate(s) for an existing rate-limited function, without creating a new function.

v0.3.9

This release includes updates to ensure a rate-limited function won't exceed its rate limit, even in the presence of network latency or imprecision in the ability to time pauses. The API is unchanged.

v0.3.7

Edit unit tests so that tests relying on microbenchmark ("Suggests") are conditional on microbenchmark's presence
