Subject: [PATCH] Remove Content-Length header from chunked response

HTTP does not allow Content-Length header to be set when Transfer-Encoding is present (https://greenbytes.de/tech/webdav/rfc2616.html#rfc.section.4.4)

When chunked, Transfer-Encoding is set. This causes issues, for example when adding the camera to HomeAssistant, since it causes an error in the http library.

This commit removes the Content-Length header in this case.
