Templ in Cloudflare workers

Uses Cloudflare's Workers and Pages service, along with a key-value store to host a templ app.

Features:

• Counters are updated without a full page reload
• Queued requests so all button presses are counted.
• Worker compiled to web assembly as Go is sadly not supported in Workers
• Uses htmx for interactivity, templ for page rendering, tinygo to compile for WASM and wrangler to deploy.
