Use a pool of browsers to execute render requests

See original GitHub issue

Currently a new chrome instance is launched for every render request, which introduces latency and the possibility of running out of memory if too many requests come in at once.

Originally this requirement was because there wasn’t a way to set the timezone for a particular page in puppeteer, but that is now available: https://github.com/puppeteer/puppeteer/blob/v2.0.0/docs/api.md#pageemulatetimezonetimezoneid

I’d suggest using https://github.com/Vincit/tarn.js to manage the pool of puppeteer browser objects so that we can easily handle multiple requests by running up to pool.max chrome instances and queuing requests until an instance is available.

Aha, that is a problem then, since the alpine packaged version in edge right now is 78.0.3904.108-r0 https://pkgs.alpinelinux.org/package/edge/community/x86_64/chromium which seems to be the current stable release as that’s the version in the ubuntu etc repos also.
