graphics: Remove SHA1 hashes for distfiles

Log message:
leptonica: updated to 1.82.0

1.82.0
* Fix issue-585: reading tiff rgb with tiffbpl = 1.5 * packedbpl.
* Fix issue-586: failure to properly wrap tiff-g4 in pdf without
  transcoding.  The fix is to do transcoding for tiff-g4, as was
  done before April 2021.

Log message:
leptonica: updated to 1.81.1

1.81.1  June 11, 2021
* Added choice of codec (JP2 or J2K) when writing jp2k files.
* Fix use of hashmap with key based on dna.

1.81.0  June 6, 2021
* Fixed problems with tiff pdf wrapping photometry.
* Fixed scaling issues in prog/cleanpdf for printing.
* New progs: tiffpdftest, hashtest
* Fixed uninitialized data error in pixAddBorderGeneral() and
  pixRemoveBorderGeneral()
* Rewrote Numa functions that discretize into bins.  Have
  binning by both sorting and histogram.
* Rewrote and simplified pixGetRankColorArray() and pixGetBinnedColor().
* Added tests to prog/rankbin_reg.c.
* Simplified fpixCopy() and dpixCopy(), and functions that use them.
* Check input for bilateral transforms.
* Add function for splitting a file evenly by lines.
* Check input for getFilenamesInDirectory()
* Many new fuzzers.
* Use size_t for all size inputs to ascii85 encoding/decoding
* New regression tests: encoding_reg.c, binmorph6_reg.c,
  flipdetect_reg.c
* Reworked concatpdf for generality, using the Poppler package.
* Removed dwa flipdetection from the library.  All the dwa code
  is now in flipdetectdwa.c.notused.  Likewise prog/flipselgen.c
  is retained for completeness, renamed flipselgen.c.notused,
  and is not compiled.
* Added hashmap utility (hashmap.c, hashmap.h).
* Removed functions using dnahash on strings, pts and doubles.
* Improved the speed of hashing for strings and doubles.
* Added function for tiling images in pairs for comparison.
* Added null terminations to serialized strings written to memory,
  preventing buffer overrun by strlen() [fixed by Stefan Weil].
* No longer use "NoInit" versions of pix creation in leptonica.
  because they risk reading uninitialized data.  These functions
  remain in the library because they are in use in applications.
* Add two composite binarization functions, from prog/binarize_set.
* Giulio Lunati fixed pnm reading to work with stdin input.
* Removed several of the boxa compare and modify functions.
* Implemented reading jpeg200 data encded in j2k "codestream" format.
  Can now read data in both jp2 and j2k.

leptonica: updated to 1.77.0

1.77.0:
Here is the current status of CVE issues with leptonica; see
  https://security-tracker.debian.org/tracker/source-package/leptonlib
* CVE-2018-7442: potential injection attack because '/' is allowed
  in gplot rootdir.
  Functions using this command have been disabled by default in the
  distribution, starting with 1.76.0.  As for the specific issue, it
  is impossible to specify a general path without using the standard
  directory subdivider '/'.
* CVE-2018-7186: number of characters not limited in fscanf or sscanf,
  allowing possible attack with buffer overflow.
  This has been fixed in 1.75.3.
* CVE-2018-3836: command injection vulnerability in gplotMakeOutput().
  This has been fixed in 1.75.3, using stringCheckForChars() to block
  rootnames containing any of: ;&|>"?*$()/<
* CVE-2017-18196: duplicated path components.
  This was fixed in 1.75.3.
* CVE-2018-7441: hardcoded /tmp pathnames.
  These are all wrapped in special debug functions that are not
  enabled by default in the distribution, starting with 1.76.0.
* CVE-2018-7247: input 'rootname' can overflow a buffer.
  This was fixed in 1.76.0, using snprintf().
* CVE-2018-7440: command injection in gplotMakeOutput using $(command).
  Fixed in 1.75.3, which blocks '$' as well as 11 other characters.
Wrapped the few 'system' calls in an extra layer of debug code.
More coverity scan fixes; defects are about 1 per 10,000 source lines.
New regression tests: numa1_reg, numa2_reg, lowaccess_reg,
  pixmem_reg.
New non-regression test programs: histoduptest
