Simple video/audio Record Demo Using mediasoup 3 and GStreamer/FFmpeg

---

Introduction

Simple video/audio record application using Mediasoup and GStreamer

Recorded files are stored in the server's files directory or the directory set by the user (via process.env.RECORD_FILE_LOCATION_PATH)

File names are simply the current timestamp

This sample currently only uses VP8/opus and the output file is .webm
