with this, the combining methods can combine both a board and user
config into one binary, which is a step closer to having a command that
does it, and then we can start removing BoardConfig.h from the firmware
build and replace it with patched binaries.
to test it, another retrieval method was added too, and this will
probably be used for more dump commands or a better info or something
like that
