Touch compatibility for audio tools

[ghost]

I played with the editor on an 7-inch Android Tablet and the Select audio region and Shift audio in time tools are not touch compatible. Maybe not on top of priority list, but might be useful in some projects.

Thank you @naomiaro for waveform playlist !
I discovered it with Logimix (https://ladigitale.dev/logimix/#decouvrir)
Now we're trying to integrate it into dodoc ( https://github.com/l-atelier-des-chercheurs/dodoc).
But waveform is not compatible with touch interfaces.

It would be really nice if the Select audio and Shift audio also worked on tablets or interactive whiteboard.
