⚡ Automatically call middleware dependencies

[DaniFoldi]

This PR implements

• a new system to invoke middleware, so their dependencies are automatically invoked beforehand, and no middleware is called twice
• some improvements to the response formatting system, so returning an ArrayBuffer/Blob now also works, and if a content-type header is set (and non-json), the JSON.stringify call is bypassed. This can be used for HTML responses, for example.

Besides that

• dependencies were updated
• the eslint preset was migrated to the new system
• and all lint errors and warnings were fixed
