@actualwave/use-element-size

React hook that watches for changes in element size using ResizeObserver and reports updates forcing component to render.
There are two hooks in this package
* useResizeObserver(handlerFn, elementRef) -- Calls handlerFn() when element size changed with instance of DOMRectReadOnly.
* useElementSize(elementRef, reinitInEffect = true) -- Returns element size or null if elementRef.current does not contain reference to HTMLElement. reinitInEffect forces immediate re-render to apply element sizes, expected to have a valid reference at the time of re-render.
