Head Request Function

[thomascjohnson]

Hey folks, thank you for making this extension. Usually I'd just make a PR on my own but I'm many years removed from writing C++. It would be super helpful to have a http_head function for getting headers without having to do an entire download.

Hey @thomascjohnson sounds possible - could you expand on the request and proposal with an example?

Ok, I ended up biting the bullet and putting this quick and dirty implementation together (with a test for http_head -- all tests pass): https://github.com/thomascjohnson/duckdb-extension-httpclient/tree/http_head

Let me know what you think. Something needs to be done about generating the response string, as I didn't want to reuse GetJsonResponse with the body key.
