Compilation failed: PROJECTLIBDEPS_DIR should be PROJECT_LIBDEPS_DIR

Hi @puuu thank you for this great project. I'm working on a new protocol for my 433 MHz doorbell. I want to use an ESP8266 running MQTT433gateway to test my new protocol. When I tried to manually compile the (unmodified) source code, I ran into this error message:

I also found this https://github.com/rjwats/esp8266-react/issues/56 so I just tried to change PROJECTLIBDEPS_DIR to PROJECT_LIBDEPS_DIR on line 30 of ./scripts/fw_version.py and that worked:

I didn't want to create a pull request yet, since I expect that is was running without problems using "PROJECTLIBDEPS_DIR" in your configuration.

What do you think?

Kind regards, woutput
