Add more supports for apple pencil

Add more support for apple pencil, such as pressure sensitivity, double tap to switch between pen and eraser functions like goodnotes or onenote app.

We’ve added support for double-tapping Apple Pencil 2 to switch to the eraser in version 1.0.11.

Lovely, more "goodnote-tool" would be great though (like the lasso tool or the pen size selection). Thank you!
