• Resolves Show firmware version in device #169
• Closes #

Description

I made the splash screen into a new mode with multiple screens that you can cycle through by tapping like any other mode. Currently there are 2 states, logo and info.
I added the "info" screen which at the moment just displays the firmware version.
Created a version define that we can override at compile time in the build process to use the actual release version.

Disclaimer
I had to use 3 separate defines for major, minor and patch instead of a string because the arduino-cli does not support string type defines due to a bug (arduino/arduino-cli#846 (comment))
