 let's flash it using a `curl` command and a saved API key. The best way is
 to add a Makefile target for testing, and let Github Actions (our software CI)
 call it:

 Note that we pass a `VCON_API_KEY` environment variable to `make`. Also note
 that we're invoking `test` Makefile target, which should build and test our
 firmware. Here is the `test` Makefile target:

 Explanation:
 - line 34: The `test` target depends on `build`, so we always build firmware
