peer-calls/peer-calls: Group peer to peer video calls for everyone written in Go and TypeScript

Peer Calls is a group peer-to-peer video calling application written in Go and TypeScript. The new version includes a rewritten server in Golang, an optional Selective Forwarding Unit (SFU) for reduced bandwidth usage, and numerous features and fixes like improved file sending, device management, and toolbar layout. It supports dynamic stream handling, multiple nodes, and end-to-end encryption. Deployment can be done via Docker or using kubectl with a YAML config file. Redis can be utilized for load balancing, and a TURN server can be configured for better connectivity behind firewalls.
