Add a 'noWebWorker=true' option to <replay-web-page> embed to disable loading in separate web worker (#102)

* add a 'noWebWorker' option to <replay-web-page> embed to disable the default webworker-based loading, and load via the service worker directly. this feature was previously available, but turned-off, as its less efficient (uses sw for what can be done in a separate web worker thread). however, service-worker based loading may be needed for certain edge cases (see #97), and this option enables this loading method to be turned back on for embedding.
* docs: update guide to include 'noWebWorker', also use include attribute for boolean attributes
* update CHANGES.md
* bump to 1.5.12
