Improvement suggestion: add_build_folder

[robpower]

Slight modification to have all firmware output filess (.bin, .bin.gz) sent to a selected folder. Being a separate folder could improve common maintenance/update operations:

• preventing accidentally exposing the whole code and setting when using webOTA;

• not requiring to manually copy the file to a different folder. I hope it could be appreciated, feel free to discard otherwise

  • Added buildsdir variable (defaults to ./builds) to save all the compiled firmware
  • Added gzip compression when compiling selected firmwares (compression only worked when run with no parameters)
  • Updated .gitignore accordingly

build_output/firmware is the default folder where binaries are copied after compiling. this container's purpose is to be default settings only.

if you want to move binaries after compiling you can easily do it with another bash script. i do it that way!

binaries placed in build_output folder are already both gzipped and in .bin format
