Playground: Throttle URL updates to avoid replaceState limit

[marcoroth]

This pull request updates the playground to throttle its URL updates so that typing quickly in the editor no longer trips the browser's history.replaceState() rate limit.

Every keystroke called four separate URL writers. Each of them built its own URL and unconditionally called window.parent.history.replaceState(), even when the search params were already identical to what was in the URL. That adds up to four replaceState() calls per keystroke, so Safari's limit of 100 calls per 10 seconds is reached after roughly 25 characters of fast typing:

Unhandled Promise Rejection: SecurityError: Attempt to use history.replaceState() more than 100 times per 10 seconds

Because the SecurityError is thrown from inside updateURL(), which is the first thing analyze() does, the rejection aborts the whole analysis and the playground stops responding to further input.
