Version compiled FW with automatic macro (#267)

* Version compiled FW with hash

Auto generates a macro to type out version info, local and github compilation now includes commit hash and timestamp in final uf2 files

* Fix local builds

makefile doesn't like the script returning the macro, directed to null for local builds as version.dtsi file accessible
