devel/difftastic: update to 0.58.0

0.58 (released 11th May 2024)
Parsing
 - Difftastic now preserves tree-sitter parse tree structure on parse error
   nodes. This reverts the flattening behaviour introduced in 0.38. Preserving
   structure tends to produce better diffs, although it increases the risk that
   difftastic will show fewer changes in the presence of parse errors.
 - Since difftastic is now conservative with parse errors (DFT_PARSE_ERROR_LIMIT
   is 0 by default), this seems like a better tradeoff.
 - Updated C, C++, CMake, CSS, Elm, Go, Lua and Python parsers.

Diffing
 - --strip-cr now defaults to on, so comparing a file with CRLF endings with a
   file with unix line endings will not show spurious changes.

Documentation
 - Difftastic now has a man page, see the difft.1 file.

Performance
 - Fixed a memory leak and improved performance in some cases.

Command Line Interface
 - Fixed a crash when difftastic could not detect the terminal width, such as
   inside eshell.
 - Difftastic now also considers $COLUMNS when detecting the terminal width.
