CLI library list not complete?

Hi,

I've noticed that the list of libraries available in the CLI is not complete. Because of this, the CLI doesn't download dependencies that are actually necessary for a library. Consider this example:

> h5p get h5p-blanks
Looking up dependencies... DONE
Cloning into 'h5p-blanks'... OK
Cloning into 'font-awesome'... OK
Cloning into 'h5p-joubel-ui'... OK
Cloning into 'drop'... OK
Cloning into 'tether'... OK
Cloning into 'h5p-font-icons'... OK
Cloning into 'h5p-transition'... OK
Cloning into 'h5p-question'... OK

However, the library.json file of h5p-blanks specifies further dependencies on H5P.TextUtilities and H5PEditor.RangeList. These are not downloaded with the CLI as they are not in the list. 

Would it be possible to update the list of libraries supported by the CLI?
