Add a codespell check

Only 2 typos found. Great.
Thanks for the GitHub actions file. I am not familiar with these actions (yet).
Do you know if there is an Arduino build task available to check compilation results or source code static analysis?

Yeah not too much to know with a built action like the codespell one, just some program specific config (like if you were running it on the CLI). Compared to running the tool yourself where the action would have to download and install lots of stuff.

The lack of other typos may be because I'd added a codespell run to Travis and fixed them at that point:

I think so, you could start by turning on Travis (.org or .com, despite their claims the former still appears to be alive):

The next easiest thing is probably just to port the existing Travis PlatformIO config to Github:

DmxSerial2/.travis.yml

Lines 14 to 23 in 854fb21

	matrix:
	fast_finish: true
	include:
	- env: BOARD=teensy20 PLATFORMIO_CI_SRC=examples/RDMSerialRecv
	- env: BOARD=teensy20pp PLATFORMIO_CI_SRC=examples/RDMSerialRecv
	- env: BOARD=uno PLATFORMIO_CI_SRC=examples/RDMSerialRecv
	- env: BOARD=diecimilaatmega328 PLATFORMIO_CI_SRC=examples/RDMSerialRecv

	- env: BOARD=nanoatmega328 PLATFORMIO_CI_SRC=examples/RDMSerialRecv
	- env: BOARD=pro16MHzatmega328 PLATFORMIO_CI_SRC=examples/RDMSerialRecv

DmxSerial2/.travis.yml

Line 35 in 854fb21

- if [[ "$TASK" != "codespell" ]]; then pip install --upgrade platformio; fi

DmxSerial2/.travis-ci.sh

Line 28 in 854fb21

platformio ci --lib="." --board=$BOARD

But I'll see if I can find the Arduino actions, I was talking to some of their people about codespell a while back.

It looks like @per1234 has indeed worked their magic, see for example:
https://github.com/arduino-libraries/Arduino_APDS9960/tree/master/.github/workflows

Which I'll open a new PR to test out... #35

I think we all got a bit distracted with the other actions in #35 and beyond. Can this be merged as is given it's distinct from them?
