Add support for libspnav on Linux and MacOS

On Linux and MacOS, libspnav provides access to spacemice including legacy serial (not USB) devices. This release allows RawMouse to use those devices instead of a HID device.

Minor tweaks

Just a few minor changes and added the Space Mouse Enterprise device.

Fixed Universal Receiver issue (again)

Fingers crossed I got it right this time!

Provide an alternative faster view when the layer view is moved

To speed up movement when the layer view is displayed, holding down the CTRL key will now flip to a simple and fast view for the duration of the movement.

Please note that due to the addition of the FastView plugin, the RawMouse plugin has moved to a sub-directory.

Become focus aware

Now ignores mouse events when Cura loses the focus.

I've only tested this on Linux, if there's a problem on the other platforms, please open an issue.

Fix Universal Receiver on MacOS

Added another devices line for the Universal Receiver matching the usage_page and usage on MacOS.

Added roll axis

Added roll axis (target "rotroll") and renamed targets "rotx" to "rotyaw" and "roty" to "rotpitch". The old rotx/roty names are still usable.

Now displays more information about device in message box.

Fix Universal Receiver Issue

Fixed the Universal Receiver not working on Windows (and, hopefully, MacOS but that's not been tested yet).

Fixed meta data blunder

Updated plugin.json.

Initial release

Basic functionality in place and tested.
