Get more-up-to-date PCTA closures data

[mileswwatkins]

It appears that the PCTA website, the only source for closure and hazard notices (not apparently republished on Twitter, etc), now has Cloudflare/hCAPTCHA anti-bot code.

I'm communicating with the PCTA tech lead to see if there's a better/another way to access this data, but for now I'm scraping the Google cache (usually ~24–48 hours old) for this information. A longer term solution could be a daily/hourly AWS Lambda using Puppeteer headless Chrome to try avoiding Cloudflare bot detection, or a paid service to get past the hCAPTCHA. Neither are particularly desirable paths; let's hope that the PCTA has an official solution.
