Automatic device import using open fixture library

[Arian-Ott]

Rationale

Open fixture library is well maintained and an open standard for fixture definition. Using OFL will enable hyperion to use crowd sourced fixture definitions without relying on commercial options. Furthermore OFL offers a fair amount of plugins to convert OFL fixture definitions in other formats.

Objective

Currently Hyperion has a hardcoded list of Manufacturers generated by gemini.
Goal is to automate the import using https://github.com/OpenLightingProject/open-fixture-library/blob/master/fixtures/manufacturers.json.

• Remove the hardcoded list with an auto import of manufacturers
• Add automatic device import to hyperion (including channel names)
