fonts/ruby-ttfunk: update to 1.8.0 

1.8.0 (2024-03-05)

Fixed

* Corrupted CFF index data

  there was a subtle bug in cff index implementation that resulted in a data
  corruption.  in certain circumstances some items didn't get properly
  encoded.  this happened when items were not previously accessed.

  this resulted, for instance, in missing glyphs.  but only sometimes
  because indexes might've still contain data that shouldn't've been there.
  in combination with incorrect encoding (see further) this resulted in some
  glyphs still being rendered, sometimes even correctly.

  along with the fix a rather large api change landed.  this resulted in
  quite a big diff.

  Alexander Mankuta

* Incorrect CFF encoding in subsets

  TTFunk used to reuse encoding from the original font.  This mapping was
  incorrect for subset fonts which used not just a subset of glyphs but also
  a different encoding.

  A separate issue was that some fonts have empty CFF encoding.  This
  incorrect mapping resulted in encoding that mapped all codes to glyph 0.

  This had impact on Prawn in particular.  PDF spec explicitly says that CFF
  encoding is not to be used in OpenType fonts.  cmap table should directly
  index charstrings in the CFF table.  Despite this PDF renderers still use
  CFF encoding to retrieve glyphs.  So TTFunk has to discard the original
  CFF encoding and supply its own.

* maxp table

  The table is now correctly parsed and encoded for both TrueType and
  CFF-based OpenType fonts.

* Files are closed sooner

  Files were garbage collected but could stay open for longer than necessary.

  Jon Burgess

* Long date time in the head table

  The created and modified fields we parsed and encoded with incorrect
  endiannes.  Additionally helper methods were added to convert these fields
  to and from Ruby Time.

  Jens Kutilek, Peter Goldstein

* Removed execution permissions on non-executable files
