Float/double data not supported by DicomWriter

[melissalinkert]

See https://forum.image.sc/t/exporting-a-dicom-stack/99400/9.

I can easily reproduce the exception noted with Bio-Formats 7.3.1 and:

$ bfconvert "test&pixelType=float.fake" test-float.dcm

Updating the getPixelTypes method to include FormatTools.FLOAT is necessary but not sufficient; additional changes to metadata are needed as indicated in https://dicom.nema.org/medical/dicom/current/output/chtml/part03/sect_C.7.6.24.html.

Note that floating point data would only be possible to support for uncompressed output, which in practice means non-WSI data only.
