devel/ruby-regexp_parser: update to 2.5.0

[2.5.0] - 2022-05-27 - Janosch Müller

Added
* Regexp::Expression::Base.construct and .token_class methods
  o see the wiki for details

[2.4.0] - 2022-05-09 - Janosch Müller

Fixed
* fixed interpretation of + and ? after interval quantifiers ({n,n})
  - they used to be treated as reluctant or possessive mode indicators
  - however, Ruby does not support these modes for interval quantifiers
  - they are now treated as chained quantifiers instead, as Ruby does it
  - c.f. #3
* fixed Expression::Base#nesting_level for some tree rewrite cases
  - e.g. the alternatives in /a|[b]/ had an inconsistent nesting_level
* fixed Scanner accepting invalid posix classes, e.g. [[:foo:]]
  - they raise a SyntaxError when used in a Regexp, so could only be
    passed as String
  - they now raise a Regexp::Scanner::ValidationError in the Scanner

Added
* added Expression::Base#== for (deep) comparison of expressions
* added Expression::Base#parts
  - returns the text elements and subexpressions of an expression
  - e.g. parse(/(a)/)[0].parts # => ["(", #<Literal @text="a"...>, ")"]
* added Expression::Base#te (a.k.a. token end index)
  - Expression::Subexpression always had #te, only terminal nodes
    lacked it so far


* made some Expression::Base methods available on Quantifier instances, too
  - #type, #type?, #is?, #one_of?, #options, #terminal?
  - #base_length, #full_length, #starts_at, #te, #ts, #offset
  - #conditional_level, #level, #nesting_level , #set_level
  - this allows a more unified handling with Expression::Base instances

* allowed Quantifier#initialize to take a token and options Hash like
  other nodes

* added a deprecation warning for initializing Quantifiers with 4+ arguments:

  Calling Expression::Base#quantify or Quantifier.new with 4+
  arguments is deprecated.

  It will no longer be supported in regexp_parser v3.0.0.

  Please pass a Regexp::Token instead, e.g. replace token, text, min,
  max, mode with ::Regexp::Token.new(:quantifier, token, text).  min,
  max, and mode will be derived automatically.

  Or do exp.quantifier = Quantifier.construct(token: token, text: str).

  This is consistent with how Expression::Base instances are created.

[2.3.1] - 2022-04-24 - Janosch Müller

Fixed
* removed five inexistent unicode properties from Syntax#features
  - these were never supported by Ruby or the Regexp::Scanner
  - thanks to Markus Schirp for the report

[2.3.0] - 2022-04-08 - Janosch Müller

Added

* improved parsing performance through Syntax refactoring
  - instead of fresh Syntax instances, pre-loaded constants are now re-used
  - this approximately doubles the parsing speed for simple regexps
* added methods to Syntax classes to show relative feature sets
  - e.g. Regexp::Syntax::V3_2_0.added_features

* support for new unicode properties of Ruby 3.2 / Unicode 14.0
