ast 1.0.13

Extension exposing PHP 7 abstract syntax tree

php-ast exports the AST internally used by PHP 7.
php-ast is significantly faster than PHP-Parser, because the AST construction is implemented in C.
However, php-ast may only parse code that is syntactically valid on the version of PHP it runs on.

Changes

- Indicate in metadata that 'AST_CLASS_CONST_GROUP' and 'AST_CLASS_CONST_DECL' can have MODIFIER_FINAL
(and any modifier a class element can have, to reflect what the parser can actually parse)
- Support php 8.1 intersection types, add node kind 'AST_TYPE_INTERSECTION'
