larger item metadata stream chunks, fixes #1452

Browse source 
increasing the mask (target chunk size) from 14 (16kiB) to 17 (128kiB).
this should reduce the amount of item metadata chunks an archive has to reference to 1/8.
this does not completely fix #1452, but at least enables a 8x larger item metadata stream.
