This PR introduces two type alias to avoid the confusing const generic `pub struct Codegen<'a, const MINIFY: bool>` * CodeGenerator - Code generator without whitespace removal. * WhitespaceRemover - Code generator with whitespace removal. Usage is changed to a builder pattern: ```rust CodeGenerator::new() .enable_comment(...) .enable_sourcemap(...) .build(&program); ```
