pliCount is Picture Loss Indication, not Packet Loss Indication

[henbos]

Our spec says pliCount is...

Count the total number of Packet Loss Indication (PLI) packets received by the sender. This metric is only valid for video and is sent by receiver. Calculated as defined in [RFC4585] section 6.3.1.

PLI is actually Picture Loss Indication, https://tools.ietf.org/html/rfc4585#section-6.3.1.
