support compiling bin file

[trackhacs]

compilation of bin file is an essential part of klipper. therefore it would be necessary to install klipper parallel to this docker and essentially void the advantage of this docker.

please consider this as feature request to include the ability to compile the bin files inside of the container - as this would increase the usability significant.

I'm not sure if @dimalo attempted this, but I gave it a shot. The environment required to compile the firmware is much larger than the environment needed to run Klipper. So the resulting image is huge. It could be done as a separate image though.
