tiff: update to 4.2.0.

MAJOR CHANGES:

    Optional support for using libdeflate is added.
    Many of the tools now support a memory usage limit.

CHANGES IN LIBTIFF:

    A great many issues discovered by fuzzers (via oss-fuzz and other reports) have been addressed.
    EXIF 2.32 and GPS tags and functionality have been upgraded:
        Existing EXIF field definition of tags are upgraded to EXIF version 2.3.2
        EXIF-GPS structure, tags and access functions are added as special CustomDirectory (like it was done for EXIF).
        Reading error for FileSource and SceneType tags corrected.
    Make TIFFTAG_CFAPATTERN variable count.
    Cmake configuration fixes for big-endian targets.

    Added support for optional building against libdeflate for faster Zip/Deflate compression/decompression.

    We now have 2 kinds of builds with the Zip/Deflate codec:
        zlib only
        zlib + libdeflate

    Speed improvements in the 35%-50% range can be expected when libdeflate is used. Compression level up to 12 is now supported (capped to 9 when zlib is used). Still requires zlib for situations where libdeflate cannot be used (that is for scanline access, since libdeflate has no streaming mode)

    Pseudo-tag TIFFTAG_DEFLATE_SUBCODEC=DEFLATE_SUBCODEC_ZLIB/DEFLATE_SUBCODEC_LIBDEFLATE is added to control which subcodec (zlib or libdeflate) should be used (it defaults of course to libdeflate, when it is available). This is mostly aimed at being used on the writing side, to be able to reproduce output of previous libtiff versions at a binary level, in situations where this would be really needed. Or as a safety belt in case there would be unforeseen issues with using libdeflate. It can be used to know when libdeflate is available at runtime (DEFLATE_SUBCODEC_LIBDEFLATE will be the default value in that situation).

    Of course, deflate codestreams produced by libdeflate can be read by zlib, and vice-versa.

CHANGES IN THE TOOLS:

    A great many issues discovered by fuzzers (via oss-fuzz and other reports) have been addressed.
    ppm2tiff: support any bps value from 1 to 16.
    tiff2ps, tiff2rgba: A default memory limit is now enforced (256MiB) and a '-M' option is added to allow the user to adjust the limit.
    tiff2pdf, tiffcp: A default memory limit is now enforced (256MiB) and a '-m' option is added to allow the user to adjust the limit.
    tiffcrop: A default memory limit is now enforced (256MiB) and a '-k' option is added to allow the user to adjust the limit.
    tiff2pdf: fix "raw" copy of Deflate streams.
    tiff2pdf.c: properly calculate datasize when saving to JPEG YCbCr
    tiffcp: disable strip chopping when trying to convert to JBIG compression
