Upgrade from 1.0.x to 2.0.x

The NamedArgumentConstructorAnnotation has been removed. Use the @NamedArgumentConstructor annotation instead.
SimpleAnnotationReader has been removed.
DocLexer::peek() and DocLexer::glimpse now return Doctrine\Common\Lexer\Token objects. When using doctrine/lexer 2, these implement ArrayAccess as a way for you to still be able to treat them as arrays in some ways.
CachedReader and FileCacheReader have been removed.
AnnotationRegistry methods related to registering annotations instead of using autoloading have been removed.
Parameter type declarations have been added to all methods of all classes. If you have classes inheriting from classes inside this package, you should add parameter and return type declarations.
Support for PHP < 7.2 has been removed
PhpParser::parseClass() has been removed. Use PhpParser::parseUseStatements() instead.
