Support for Roon INVOLVEDPEOPLE field, to provide smoother importing into Roon of credits for Flac files.
So users dont inadvertently use PERFORMER field when using with Roon (see https://community.roonlabs.com/t/improved-credit-support-in-roon-1-7/84297/19 ) would be good to add Roon versions of standard Default that don't write to PERFORMER (or PERFORMER_NAME as well for consistency)
Also need to check the profiles provided for Melco are correct
Added new field and made amendments
Added new profile Roon, Fix Songs
Added involvedpeople to the list of fields to not modify for Melco profiles
FixSongs :Never modify or add these fields
AddArtworkOnly:Never modify or add these fields
AddNewMetadataOnly:Never modify or add these fields
Fixed.
