fix: remove padding wrappers (#57)

BREAKING CHANGE:
The resize observer logic is rewritten to no longer require wrapper elements like `[data-rsbs-footer-padding]`. If you're not using custom CSS and are simply importing `react-spring-bottom-sheet/dist/style.css` in your app then this isn't a breaking change for you.


If you're using custom CSS, here's the breaking changes:
- `[data-rsbs-header-padding]` removed, update selectors to `[data-rsbs-header]`
- `[data-rsbs-content-padding]` removed, update selectors to `[data-rsbs-scroll]`
- `[data-rsbs-footer-padding]` removed, update selectors to `[data-rsbs-footer]`
- `[data-rsbs-antigap]` removed, update selectors to `[data-rsbs-root]:after` and make sure to add `content: '';`.
- `[data-rsbs-content]` is changed, update selectors to `[data-rsbs-scroll]`.
- The `<div style="overflow:hidden;">` wrapper that used to be between `[data-rsbs-content]` and `[data-rsbs-content-padding]` is now within `[data-rsbs-scroll]`, and no longer hardcode `overflow: hidden`, add `[data-rsbs-content] { overflow: hidden; }` to your CSS.
