add release 7.9 to "firmware"-folder

[4ch1m]

@tjanas, could you please add the new release (v7.9) to the firmware folder?

Thanks a lot! :+1:

It seems there is a new repository for these releases. Probably because SmokeMonster doesn't want to manage them anymore. Doesn't hurt to have them here though as long as the repository stays up.
