Canon CR3 raw support - your move

It looks like the ISOBMFF support is no longer the milestone for 0.27.4 so no CR3 support in 2021?

**Is your feature request related to a problem? Please describe.** Exiv2 does n…ot support ISOBMFF format, therefore doesn't support AVIF, HEIF, CR3 and possibly other filetypes using this format **Describe the solution you'd like** Ideally - ISOBMFF format support, at least reading data from it :) **Describe alternatives you've considered** ExifTool and couple other open source projects already support ISOBMFF based files, however exiv2 still doesn't. **Additional context** Iam fully aware of #1066 - I asked my legal counsel and gethered much needed advice. According to all info I managed to gather, there's no legal issue in creating and using a tool capable of reading data and metadata stored in ISOBMFF containers. Worth noting is the fact that JPEG2000 IS an ISOBMFF based and support for it is present in the library without any issue. Aditionally, already existing libraries like libavif, libheif, libraw and others already work with ISOBMFF files without legal problems. The ONLY problematic issue would be not reading but decrypting encrypted (not encoded) data or using proprietary code, which I am sure is not the issue here.
