* Replace relative URLs with absolute URLs when stringifying stylesheets
* Add test to show desired behavior for imported stylesheets from seperate directory
* Rename `absoluteToStylesheet` to `absolutifyURLs` and call it once after stringifying imported stylesheet
* Don't create the intermediary array of the spread operator
* Formalize that `stringifyRule` should expect a sheet href
* Ensure a <style> element can also import and gets it's url absolutized
* Handle case where non imported stylesheet has relative urls that need to be absolutified
* Clarify in test files where jpegs are expected to appear in absolutified urls
* Move absolutifyURLs call for import rules out of trycatch
* Add a benchmarking test for stringifyStylesheet
* Avoid the duplication on how to fall back
