canon_cr3: mapping Canon CR3 camera files

canon_cr3 maps Canon camera image files, especially the CR3 container and its CRX image structures. Its format notes describe tracks, custom tags, metadata and compression, while a Python parser inspects CR3 and CR2 files and extracts selected image parts. Separate notes describe Canon HEIF images.
