Add absolute beats reporting

[justcfx2u]

Add inverse of OSC /time.

This feature allows number of beats to be get/set.

• /time (set absolute transport position in beats; feature already exists)
• /beats/current (get absolute transport position in beats; this feature)

Sorry, for the late reply, I somehow missed your pull request. Is there an actual difference between playPosition () and this.transport.playStartPosition () ?

There is! I am writing an external companion sequencer for BitWig using DrivenByMoss.

resources/doc/control-surface/api/com/bitwig/extension/controller/api/Transport.html#playPosition() returns a BeatTimeValue() which extends DoubleValue. Therefore, playPosition() is a VERY accurate position of the song in total number of beats. This is useful through tempo changes, time signature changes, etc. and is updated in real time as the transport plays.

playStartPosition() reports a static value which does not change during playback.
"/time/str" calls getPositionText which calls getFormatted which coerces it to a string.

Therefore, this feature (GETS absolute position in beats, automatically updated as a subscription) combined with /time (SETS absolute position in beats), this feature allows both setting and getting the absolute position in beats which is makes following and navigating BitWig's transport into my external sequencer speak the same language (double values) while not specifically caring about the tempo, tempo changes (which would make time calculation far more complicated), or measures at all.

Ah, sorry, I ment: playPosition () and getPosition () which is already there.
