Feature Request: fcast Casting Support

Hi AntennaPod team,

I’d like to request support for fcast (https://fcast.org/) as a casting option in AntennaPod.

fcast is an open-source casting protocol that lets users stream podcasts to desktop receivers (Windows, macOS, Linux), Android devices, and Google Cast-enabled devices. It supports automatic mDNS discovery, QR-code pairing and real-time playback sync.

It’s actively developed, privacy-friendly, and I think it aligns well with AntennaPod’s open-source values. Adding it would give users a flexible, platform-independent way to cast their podcasts.

Thanks for considering!
