When upgrading to v15, I discovered some issues with `useMeasure` forcing me to downgrade to v14 again. Hopefully these changes fixes those issues...
* It was no longer possible to define the ref type, meaning components requiring a certain type of ref would reject it. Fixed this by making the function generic again.
* Previously you _had to_ define the ref type, while in v15 you _couldn't_. Fixed this by giving the generic type a default type of `HTMLElement`.
* The implicit typing of `useMeasureMock` combined with the ternary default export statement made the imported type of `useMeasure` very messy. Fixed this by making the type of `useMeasureMock` explicitly match `useMeasure`.

* resize-observer-polyfill package is not used with useMeasure() hook
anymore.
* useMeasure() now defaults all values to -1, if they were not set and
internal implementation heavily refactored.
* useAsyncFn now keeps hold of old result/error when called multiple times
* resize-observer-polyfill package is not used with useMeasure() hook
anymore.
* useMeasure() now defaults all values to -1, if they were not set and
