Provides an entry point that builds and returns a combined LH + RH keyboard firmware when provided a keymap via a POST body. Wraps compilation with ccache, and includes a pre-warmed cache of the build in /tmp/ccache. To maximize chance of a direct cache hit, changes the lambda driver to always build in /tmp/build. some back of the envelope measurements (2012 xeon e3-1230v2, nixos) clean build, no cache -> 21.308 clean build, cache -> 7.145 modified keymap, clean build, cache -> 12.127
