Feature request: add freeswitch into the repo

[nttranbao]

Hi,

This is my first post here so please forgive if it's not in the right place.

I see asterisk PBX package is in the OpnSense Repo, so would like to have "freeswitch" added in the repo too.

Currently I had freeswitch installed and running fine on the latest OpnSense 23.7.11.

If there is some work related to adding freeswitch and testing, I think I can help.

Thanks, Bao
