testing/numen: new aport

This is trying to package Numen voice control.

I've got everything compiling, including the vosk-api with system packages which improves on: !41097 (closed) That said, numen does not seem to run properly and spits out many Vosk warnings. I think this might only be a problem with openfst on i686 (my machine is i686) as I had to patch out tests when natively compiling on i686 (see i686.patch and linked issue).

Note dotool uses /dev/uinput, so you might need to run: modprope uinput

I will split it into nice commits when everything is sorted.
