Refactor tempo api, include quarter-note distance in frames method.
- moves frame rounding up to TempoMap, which is needed
in order to calculate pulse distance without frame rounding.
- the time unit for tempo is still minute, but this now also
applies to meter sections. (new audio locked meter sections no
longer require a frame position).
- there is no longer a discontinuity
in the pulse for audio-locked meter/tempi.
- temporarily add debugging output in Region::set_position()
to test for region beat not matching region frame.
