Support Netlify Edge Functions

[Ehesp]

Netlify offers an integration integartions to work with the Netlify CLI. We've got a package setup to handle this integration but it needs some love. There's a few things to figure out:

Netlify CLI first scans for generated functions, and then runs the provided build command. This means it first starts with no functions, or old ones & serves them. Once that's complete, it then runs the compiler, detects a new function and reloads. This causes a bit of a janky developer experience.

Another issue seems to be that Netlify isn't detecting file changes from a process, and thus doesn't reload the server. Manually saving the file triggers a build, so need to investigate what's going on there.
