Pyometiff

- can now choose to enable or disable BigTiff encoding with the `bigtiff` option in `OMETIFFWriter`
- minor fixes

pyometiff OMEXMLs now includes the standard declaration tag, the omission resulted in encoding errors in bftools/xmlvalid

what's new:

- version name is a cool reference to James Bond
- `OMETIFFWriter` can write .xml descriptions without outputting an entire OME-TIFF file using the `write_xml()` method

Whats new:

- **Image compression support**:
`OMETIFFWriter` has a `compression` argument that matches `tifffile.TiffWriter.save`'s `compression`, meaning that every compression scheme supported by `tifffile` is now supported in `pyometiff`
- fixed bug that raised errors when reading images with populated `Detector.Type` OMEXML field

whats new:
- fixed error in OMETIFFWriter name setting

Whats new:
- in OMETIFFWriter you can now use explicit_tiffdata=False (default) to generate a single <ome:TiffData/> tag instead of one per image plane.
