Support for rate limiting

[gkiely]

Following this tutorial: https://developers.cloudflare.com/workers/runtime-apis/bindings/rate-limit/

main = "src/index.js"

# The rate limiting API is in open beta.
[[unsafe.bindings]]
name = "MY_RATE_LIMITER"
type = "ratelimit"
# An identifier you define, that is unique to your Cloudflare account.
# Must be an integer.
namespace_id = "1001"

# Limit: the number of tokens allowed within a given period in a single
# Cloudflare location
# Period: the duration of the period, in seconds. Must be either 10 or 60
simple = { limit = 100, period = 60 }

env.MY_RATE_LIMITER is not exposed as a binding.

I tested this locally and it works for me - I get a 200 Ok in the console when running wrangler dev and calling the route with curl http://localhost:8787.

I'm going to close this for now, because I believe this works, but if you can provide an example repo that displays this behaviour then please feel free to re-open.

Other than that, the only thing I can suggest is that this is a TypeScript issue rather than a runtime issue, and it might be fixed by running wrangler types.
