Add support for version constraints in depends field

per1234 · per1234 · commit 4961340130ba · 2021-06-03T05:34:22.000-07:00
Arduino CLI and the Library Manager indexer has some provisional support for specifying version constraints in the
library.properties depends field. Although undocumented, this syntax is fully supported by the other tools, so Arduino
Lint's previous treatment of libraries using this feature as invalid is incorrect.
