Exhance TIFF format export
After working on the TIFF writer in #1649 I'm tempted to implement some additional features besides baseline TIFF export:
- compression (https://www.awaresystems.be/imaging/tiff/tifftags/compression.html)
- int32 / int16 format (https://www.awaresystems.be/imaging/tiff/tifftags/sampleformat.html)
- embedded alpha channel (https://www.awaresystems.be/imaging/tiff/tifftags/extrasamples.html)
- alpha mask & preview layer (https://www.awaresystems.be/imaging/tiff/tifftags/newsubfiletype.html)
- selectable embedded metadata
- integrate with #1650
TODO: add UI compatibility warning for non-baseline features (https://github.com/chunky-dev/chunky/pull/1661#issuecomment-1785792674)
