allow reading the stored/raw timestamp value of a Block

Given the API to get the GlobalTimecode of a Block doesn't handle the floating
point value of the TrackTimestampScale (attaching a parent track is not common
and even though the value is not directly available unlike a fractional
timestampscale), it allows external code to compute the proper timestamp
when TrackTimestampScale is not 1.0.
