graphics/unpaper: Update to 7.0.0

Changelog:

* Tests now compare a golden file by counting the bytes that differ
  between it and the result. This allows non-byte-perfect calculations
  to be executed and still not fail the tests. This is required as fused
  multiply-add instructions can increase precision and thus deviate from
  the base C code, when using floating-point arithmetic.

* Build is now provided by Meson, replacing the Autotools based build
  system introduced in 0.4, 10½ years ago.

* Compatibility expanded to ffmpeg-5 (and newer versions), which is the
  current widely available release.
