Add GUI elements to the rewinder node

Audio editors have a lot of features that could very neatly translate into the rewind node, givign the users a flexible and intuitive interface that they are already familiar with.

Allowing users to:
- Enabeling and disabeling recording,
- Pausing recording,
- Start and stop replay in the node with buttons,
- display the recorded messages on a timeline,
- allow zoom on the timeline,
- scrub forward and backwards through the data with a slider,
- fast forward and slow down, (adjust playback speed)
- select a range of the data to play,
- allow muting for parts of the data,
- allow adding new messages to the data,
- toggle single play, and loop play,
- displaying multible recorder streams side by side, and allowing to synchronize them (probably needs to be implemented as a config node, or some kind of shared contex.)
