- Added workflow triggered by cron or label "hil_test"
- Added examples with both pytest and unity

The reason behind this refactoring is that all of the sketch related functions can (and will) be used for other purposes.

Build in the sketch directory: This will make it easy to handle artifacts after the build.
Separate sketch related functions from IDE installation script. This is the main commit.
Create a separate job for the Cmake check. This check was part of one of the Linux build. I believe that it's not the best place for such a check.
Checking for the skip landmarks and validity of the the sketch directory were already done by count_sketches.
