Request to add legrand_rflc folder to the custom_integrations git so they appear in Home Assistant Devices.

Icon of an LC7001 or just the Legrand logo itself would be nice. I'm happy to source and format the needed files if you would be willing to do the pull request for the ha github location. Thank you.
