Tifffile

- Assemble IFDs in memory to speed-up writing on some slow media.
- Handle discontinued arguments fastij, multifile_close, and pages.

- Use black background in imshow.
- Do not write datetime tag by default (breaking).
- Fix OME-TIFF with SamplesPerPixel > 1.
- Allow 64-bit IFD offsets for NDPI (files > 4GB still not supported).

- Fix decoding deflate without imagecodecs.

- Update copyright year.
- Require imagecodecs >= 2018.12.16.
- Do not use JPEG tables from keyframe.
- Enable decoding large JPEG in NDPI.
- Decode some old-style JPEG.
- Reorder OME channel axis to match PlanarConfiguration storage.
- Return tiled images as contiguous arrays.
- Add decode_lzw proxy function for compatibility with old czifile module.
- Use dedicated logger.

- Make SubIFDs accessible as TiffPage.pages.
- Make parsing of TiffSequence axes pattern optional (breaking).
- Limit parsing of TiffSequence axes pattern to file names, not path names.
- Do not interpolate in imshow if image dimensions <= 512, else use bilinear.
- Use logging.warning instead of warnings.warn in many cases.
- Fix NumPy FutureWarning for out == 'memmap'.
- Adjust ZSTD and WebP compression to libtiff-4.0.10 (WIP).
- Decode old-style LZW with imagecodecs >= 2018.11.8.
- Remove TiffFile.qptiff_metadata (QPI metadata are per page).
- Do not use keyword arguments before variable positional arguments.
- Make either all or none return statements in function return expression.
- Use pytest parametrize to generate tests.
- Replace test classes with functions.

- Rename imsave function to imwrite.
- Re-add Python implementations of packints, delta, and bitorder codecs.
