Memory enhancements and PDF decompress API (#3129)

Browse Source 
# Description of Changes

- PDF split by size to check size of PDF as it splits, avoids issue were
a PDFs size is different viewed vs saved due to compression caused by
repeated data etc.
- Additionally memory enhancements for PDF load to dynamically load in
memory vs scratch
- PDF Decompress API for PDF testing
