This PR moves us from the xteink openx4 SDK to the freeink sdk from https://freeink.org. Out of the box there are NO changes needed in the firmware to support this swap, it all magically works as is. However as we support more than just the x3/x4 devices, this sdk allows us to pass env vars into the build commands to include support for other devices. As support for new hardware such as touch screens and bluetooth are added the xteink builds decide at compile time if the libraries are used or not. For example right now the freeinkui and icons libraries are in the platform.io file but as they are not used anywhere, they won't be included in the final build. Once the touch branch and sd themes branch are merged in this sdk is required for them to function correctly. All the docs for freeink are available at freeink.org/docs. x4/x3 is a single binary build unlike other devices that will build unique binaries for each device. Eventually we will want to remove a lot of the manual isx3 type stuff from our firmware and go through the boardsupport api the sdk provides as it will generalize everything into one common system that any device can support. The upcoming touch branch does a lot of this for us but this initial PR is JUST to get the sdk swapped over without any code changes to show seamless integration without any regressions.
