reserved character escape sequences for local names

[masao]

The latest combination of the rdf and rdf-turtle packages does not correctly handle the reserved character escape sequences for local names.
The combination of the past versions is fine, so some updates are causing the following problem.

gem "rdf", "3.3.1"
gem "rdf-turtle", "3.3.0"
require "rdf/turtle"
ttl = '@prefix p: <http://a.example/>. p:a\/a <http://a.example/p> <http://a.example/o> .'
rdf=RDF::Turtle::Reader.new(ttl) {|reader|
  p reader.statements
}

output:

[#<RDF::Statement:0x47964(<http://a.example/a\u005C/a> <http://a.example/p> <http://a.example/o> .)>]

The past versions (rdf 3.2.11, rdf-turtle 3.2.1):

gem "rdf", "3.2.11"
gem "rdf-turtle", "3.2.1"
require "rdf/turtle"
ttl = '@prefix p: <http://a.example/>. p:a\/a <http://a.example/p> <http://a.example/o> .'
rdf=RDF::Turtle::Reader.new(ttl) {|reader|
  p reader.statements
}

output:

[#<RDF::Statement:0x3f48(<http://a.example/a/a> <http://a.example/p> <http://a.example/o> .)>]

I had actually fixed thus bug in January, but hadn't released it. It's now released in version 3.3.1 of the rdf-turtle gem.
