c/p from the InoToCpp converter that uses scons file node path
while we write binary data as utf-8 (and assume it is utf-8!),
we only ever need this in CI and source is always relative.
with luck, this is on the safe side.
- general conversion from .ino modules into a separate .cpp files
- clean-up internal headers, place libraries into .h. guard .cpp with _SUPPORT flags
- fix some instances of shared variables instead of public methods
- tweak build system to still build a single source file via os environment variable ESPURNA_BUILD_SINGLE_SOURCE
* base envs

* minor cleanup for current git
* use pio suggestion about ldscript, reduce build_flags impact
* fix linker
* parse ${vars} instead of ignoring them
