extract_files: Add support for specifying blob sections
Sometimes the need arises to update one specific subset of blobs
while holding others steady. Introduce a way to specify the "section"
of blobs to update (obviously requires the proprietary-files to be
properly split up first)
Requires additional changes in device tree extract_files.sh to support
passing the additional arguments
