`strict` and loose mode

By default this framework operate on loose mode where `__MODE__ === "loose"`. All scripts that only have strict mode have smaller bundle size and it's organized on `strict/` folder. For example,
```html

```
will define `` that only operate on strict mode.

### `strict` mode
- [ ] Require `@bind` decorator (unlike controlled loose mode, binding work on class parent and ancestors too without traversing)
- [ ] Can be enforced via `strict` attribute when using default (loose) scripts
- [ ] `` doesn't handle inline `` and `<style>` module (where it has attribute `type=module/*`)

### loose mode
- [x] Bind class `accessor`
- [x] Bind class `get`ter/`set`ter
- [ ] Bind class field
- [x] Bind class method()
- [ ] By default, all binding apply to all class parent and ancestors (#57)
- [ ] #57 can be controlled via `traverse-depth=<uint>` attribute or `class extends traverse(...Classes).extends(Class)` helper

> 💡 **Hint**: traverse binding and binding class field can be implemented at the same time
