Eoghan Murray 585c5c7ac3 Fix some css issues with :hover and rewrite max-device-width (#1431)
* We weren't recursing into media queries (or @supports etc.) to rewrite hover pseudoclasses

* The early return meant that the stylesWithHoverClass cache wasn't being populated if there were no hover selectors on the stylesheet

 - not committing the test, but modifying the existing 'add a hover class to a previously processed css string' as follows shows the problem:

--- a/packages/rrweb-snapshot/test/rebuild.test.ts
+++ b/packages/rrweb-snapshot/test/rebuild.test.ts

         path.resolve(__dirname, './css/benchmark.css'),
         'utf8',
       );
+      cssText = cssText.replace(/:hover/g, '');

       const start = process.hrtime();
       addHoverClass(cssText, cache);

* Replace `min-device-width` and similar with `min-width` as the former looks out at the browser viewport whereas we need it to look at the replayer iframe viewport

* Add some tests to show how the hover replacement works against selector lists. I believe these were failing in a previous version of rrweb as I had some local patches that no longer seem to be needed to handle these cases

* Update name of function to reflect that 'addHoverClass' does more than just :hover. I believe this function is only exported for the purposes of use in the tests

* Apply formatting changes

* Create rotten-spies-enjoy.md

* Apply formatting changes

* Add correct typing on `getSelectors`

* Refactor CSS interfaces to include optional rules

* Change `rules` to be non optional
