drivers/sen5x: Add device driver for SEN5x

[dprigoshij]

Contribution description

• Device driver for the SEN5x environmental sensor node.
• Includes a SAUL implementation
• Includes a package to pull the corresponding embedded driver from https://github.com/Sensirion/embedded-i2c-sen5x

Testing procedure

tests/drivers/sen5x:

1. Connect a SEN5x device via i2c to a supported board
2. Navigate to tests/drivers/sen5x
3. Flash and execute the test

SAUL:

1. Navigate to examples/saul
2. Add the following to the Makefile: USEMODULE += sen5x
3. Flash the saul example and also use the target term
4. Use saul read [ID] to test the outputs

I wonder if any maintainer has access to one of these?

If you are still interested in getting this in I would suggest removing the Kconfig dependency modelling aspect and posting test results :)

Hi, if this is a problem we (TU Braunschweig) could try to send you one of ours ;)
For example sending one to HAW shouldn't be a problem.

Regarding the test results, the SEN55 outputs its measurements every two seconds. Here are three sample iterations of the test:

I'm a bit confused as to what you mean by the Kconfig dependency modelling aspect. Can you elaborate this a bit further?
