Add virtual integrations for intellifire compatible fireplaces

[jeeftor]

Proposed change

The following fireplace brands are IntelliFire Compatible - and as such I wanted to make virtual integrations for them.

If you need me to back this out and just do each integration one-by-one that's fine - but I also thought maybe because its just virtual ones I could do this as a single PR
