Hey @jhurliman , thanks for this clean library!
I wanted to define the bucket size independent from the tokensPerInterval, so I added the option.

Let me know what you think!

Thanks @mosch for the independent bucket-size proposal. I reviewed it during #105. TokenBucket already supports independent bucketSize/tokensPerInterval. RateLimiter also imposes an interval cap, so a larger bucket would not permit a larger per-interval burst. This patch additionally leaves initial content set to tokensPerInterval, which can overfill a smaller configured bucket. Keeping the feature proposal open for an explicit contract: initial fill at capacity, impossible requests bounded by both limits, and deterministic tests for smaller/larger capacities and getWaitTime. The current README now distinguishes the two limiter models.
