    Connect pion library logger with snowflake log
    
    We need to set up the pion/webrtc logger to write output to the
    snowflake log, otherwise the warnings we are getting from the pion
    library are being lost.
    
    Note: this requires go version 1.13 and later in order to use the
    `log.Writer()` function.
