Sass module support

## Feature Request

This will isolate the style of each component very well, and Sass can also make writing CSS faster.

## Implement Suggestion

component.module.scss
```scss
.box {}
.btn {}
.btn__disable {}
```

```rust
static style: Asset = asset!("/assets/component.module.scss");
rsx! {
div {
class:style.box,
button:{
class:[style.btn,style.btn__disable], // Support multiple class names can be represented by an array
"Button Text"
}
}
}
```
