sendComment cannot send more than 62 bytes, as limited by the HID report.
Sending more is prevented by vsnprintf, but change the function signature
to make it explicit that the array passed to it should be at most 62 bytes.
Add support for the LCD and using it for displaying animations.
Animations are automatically played if available for the ID of the

The code should support adding other kind of animations, for tags being
removed or for other UI interactions for example.

Handle HID, which is used to communicate with the interactive application.
Update README with details on the message structures.
