pigz already has this as -tl (test and list where testing the file reads the 
whole thing, or it can be read as "true length").  When there are concatenated 
gzip streams, pigz lists them separately.

% cat foo.gz foo.gz foo.gz | pigz -tl
compressed   original reduced  name
        13         14    7.1%  <stdin>
        13         14    7.1%  <...>
        13         14    7.1%  <...>
