## What This PR Does
- Support declaration emit with `transform()`
- Consolidate shared parsing and error reporting logic into a `TransformContext`
- Add JSDoc comments to options
I'm getting this package ready for consumption in [oxc-jest](https://github.com/oxc-project/oxc-jest).
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);
```
