Bucketing Time splits requires floorable Duration

[adrianmroz]

Hi!

When creating bucketing action for time splits, there's check for floorability of Duration: https://github.com/implydata/plywood/blob/master/src/expressions/timeBucketExpression.ts#L47

So some more interesting Durations are of the limits (P2D for example). We had generated Druid query with floorable Duration, changed Duration value inside query and send it to Druid - it worked fine.

Is it possible to loosen this requirement if Druid could support it?
