Suggestion WSF - json_select_many x number of and IfGreater and IfLess

[Florian]

json_select_many would be great if this could get the first x values from the element so json_select_many "artists" "name" " ● " "5" would get the first 5 artists only.

This is now part of Mp3tag v3.21b.

An IfLess and IfGreater function would also be useful.

Just for reference, those have been already added before.
