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.

Big thanks to Ron Kuris (@rkuris) for this contribution!
