Normalize Scroll Left

This utility library addresses the inconsistent behavior of the `Element.scrollLeft` property when an element's direction is set to Right-to-Left (RTL) across different browsers. It provides methods to detect the browser's specific `scrollLeft` implementation type (e.g., WebKit's 'default', Firefox/Opera's 'negative', IE/Edge's 'reverse') and then normalize `scrollLeft` values to a consistent, WebKit-like `0` (most left) to `100` (most right) range for both getting and setting. The current stable version is 0.2.1. Releases appear to be driven by bug fixes and feature enhancements, such as ESM support in v0.2.0. Its key differentiator is robust feature detection to abstract away browser quirks, enabling developers to work with a predictable `scrollLeft` API for RTL content, based on established patterns from jQuery plugins and Stack Overflow solutions. It explicitly handles Server-Side Rendering (SSR) environments by returning `indeterminate` or `NaN` for relevant functions, indicating non-browser execution.
