Feature: Support for making additional-metadata.xlsx easier

[moisbo]

Regular expressions for making additional-metadata.xlsx faster to write, this way we do not have extra columns just to create an @id

• For example add a column with:

isREGEX_@id

.*AUDIO_Rosa.wav

• FileNames that includes the path automatically

isFileName_@id

full file name but not the path

• Other regex matching

partial IDs
