Update webhook to send colours used by Plexamp

Plexamp uses BlurHash for the colours. You can query the server for the BlurHash value for the colours. http://IP-ADDRESS:32400/library/metadata/<ratingKey>?includeFields=thumbBlurHash,artBlurHash&X-Plex-Token=<YOUR_TOKEN> Which will return something like thumbBlurHash="TLCOIA=xs+}ts,S1EMI;Ne10I@j]" artBlurHash="LmH]n4^MoIb0}pxWSNR+sRWXWrWV" Then you decode it into the colours using the BlurHash library.
