3.1.0

This release includes new functionality (PR #31) to help consumers extract a
time.Time value out of a Version 1 UUID.

UUIDs have their own internal timestamp, which is a counter of 100ns increments
since the start of the Gregorian Calendar (00:00:00 UTC on 15 Oct, 1582). To
represent that a new Timestamp type was added, with a Time() method used to
convert the timestamp value to a time.Time value.

To extract the timestamp from a Version 1 UUID, a new package
function (TimestampFromV1) was added to extract a Timestamp out of a UUID.
If it's not a V1 UUID it returns an error.
