+Add `slimDOMOptions.headTitleMutations` option to block 'animation' on <title> tag.
+Certain old-skool sites use title scrolling to draw attention to their tab; these unfortunately generate a lot of mutations in rrweb which wouldn't be used by most replayers.
+Default for this new option is off (unless `slimDOMOptions` is set to `'all'`) as a change to the <title> tag is useful to record in single page apps, when a 'soft' navigation happens.
