When using arduino-cli as part of a larger build system, I often need to fetch build properties for a sketch at build or flash time. `arduino-cli compile --show-properties` will give me a dump of all the properties I might possibly want, but it dumps them as non-expanded templates. For example, the default avr `compiler.path` gets dumped as: `compiler.path={runtime.tools.avr-gcc.path}/bin/` I would find it hugely valuable to have an option to --show-properties that shows the properties after template substitution.
