When delete v1 tag should we check for multiple v1 tags

[IJabz]

From https://java.net/jira/browse/JAUDIOTAGGER-340

I have come across files that contain more than one V1 tag at the end of the file, jaudiotagger only removes the last one but perhaps after deleting the last one it should check again and if it finds another one delete that as well.

But this would have to be optional because an application might be using jaudiotagger to just delete additional v1 tags, whilst keeping one valid one
