* Fix `???` command, which should show the help of `?`
Due to recent changes it was not working anymore, because it was
interpreteing `???` as the help with detail=3 of the root node. This
patch limits the number of detail to 2 (which is what is already assumed
in another parts of the code anyway), so that `???` can be interpreted
as the help with detail=2 of `?`. For now this makes it work, however
there needs to be some review of the whole `?` subtree.
* Add test for ???
* Fix ??? test spaces

* Create RzCmdDesc generator from YAML file
The commands tree can be entirely described in a YAML file, that is
parsed at build-time and generates cmd_descs.c/cmd_descs.h files. The
developer then just needs to provide the handler with the proper name to
make sure things work.
* Add PyYAML to CI jobs
