srt: add additional metrics (#2962)
* first attempt at the srt metrics * Updated variables to better match mediamtx * Prometheus metrics for SRT * Update readme for SRT metrics * Switch openapi to number from float * SRT metrics metrics response fix * Make the metric test less strict, and nolint line length on the SRT metrics struct * remove nolint * move BytesSent and BytesReceived into APISRTConnMetrics * merge APISRTConn and APISRTConnMetrics * improve tests --------- Co-authored-by: slowe <slowe@clairglobal.com> Co-authored-by: aler9 <46489434+aler9@users.noreply.github.com>
