Extend precompressed support to read DICOM and write TIFF/OME-TIFF

[melissalinkert]

Opening as a draft for now, as #4181 is higher priority. This may need some updates once #4181 is merged.

I would expect basic conversions such as bfconvert -noflat -precompressed -compression JPEG input.dcm output.ome.tiff to work, where the input DICOM is part of a whole slide dataset. Tile sizes should be correctly picked up without being specified in the bfconvert options.

A few outstanding things related to this PR and #4181:

• -precompressed does still require the -compression option to be set correctly; removing that requirement could be done here
• documentation started in https://github.com/ome/bio-formats-documentation/pull/349 should be updated to include additions here and in #4181 - we may want a separate page just for this feature
