Remove wrapper for kerchunk's tiff parsing

[maxrjones]

The kerchunk TIFF parser was never functional in VirtualiZarr (e.g., #291, #526), which prompted the development of virtual-tiff. Since the kerchunk tiff wrapper was never publicly documented or tested, I propose that we remove it from the code base.

• Closes #xxxx
• Tests added
• Tests passing
• Full type hint coverage
• Changes are documented in docs/releases.rst
• New functions/methods are listed in api.rst
• New functionality has documentation

10000% Thanks for remembering about this. But the docs need to be scanned for references to remove, and replaced with links to virtual-tiff.

I used grep and claude to search for references, but none came up apart from historical references in the changelog. The table mentioning this parser was previously updated in #810.

Great, thanks for checking.
