Support for multiple streams

[darkdrgn2k]

Using HLS from nginx-rtmp server it is possible to creates a multiple stream environment (ie multiple room setup)

setting different streamkeys per obs instance, nginx-rtmp will creates seperate STREAMEKEY.m3u8 file and STREAMKEY-nnn.ts files in the hsl directory.

Following updates to process-stream.sh file would need to be done to support this

• create loop to iterate through all m3u8 files in the hls folder
• run processing script against every m3u8 file
• rename current.m3u8 and live.m3u8 files to represent stream names
• if using ipns create IPFS crypo key per stream and use that
• announce multiple streams in player
