Provide a Debian / Ubuntu package for ectool?

[nealmcb]

The util/ectool utility seems to be the only way to read the fan speed on some Framework models: Fan speed - where is it reported to the OS? - Framework Laptop 13 / Linux - Framework Community)

It would be great if Framework supported the ectool as a package in Debian / Ubuntu, so we didn't have to compile it ourselves.

Since this repo is so large, I ended up using the extract of ectool at https://gitlab.howett.net/DHowett/ectool.git and figuring out how to build it with cmake, despite that being a bit nonstandard according to ChatGPT since it doesn't rely on a build directory.

cmake .
make
src/ectool help
