Sean Anderson 1f2a86393f image_types_sparse: backport generate "don't care" chunks
By default, img2simg will only generate raw and fill chunks. This adds
support for "don't care" chunks, based on file holes. This is similar to
how bmaptool works. "don't care" chunks do not need to be written,
speeding up flashing time.
This change corresponds to upstream  9862a017fa7f88424f0670ba89af58e5051550b0
