Merge pull request #146 from carloskiki/mouse-coord-type

Rework of `UseMouseCoordType`

CHANGELOG.md

@@ -10,6 +10,7 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - Updated to web_sys 0.3.70 which unfortunately is breaking some things.
 - `use_clipboard` doesn't need the unstable flags anymore.
 - `use_locale` now uses `unic_langid::LanguageIdentifier` and proper locale matching (thanks to @mondeja).
+- Removed `UseMouseEventExtractorDefault` and reworked `UseMouseCoordType` (thanks to @carloskiki)
 - `use_preferred_dark` and `use_color_mode` now try to read the `Sec-CH-Prefers-Color-Scheme` header in SSR.
