* cts support * better cjs/cts type checking * deno compile cjs/cts support * More efficient detect cjs (going towards stabilization) * Determination of whether .js, .ts, .jsx, or .tsx is cjs or esm is only done after loading * Support `import x = require(...);` Co-authored-by: Bartek Iwańczuk <biwanczuk@gmail.com>
