Investigate csvutil for CSV creation

[Mzack9999]

httpx version:

main|dev

Current Behavior:

Response data is excluded by default in CSV output as per https://github.com/projectdiscovery/httpx/issues/1914 without the possibility to reintroduce it.

Expected Behavior:

Investigate replacing standard csv library with something like https://github.com/jszwec/csvutil which handles automatically tags such as omitempty and automatic header creation, which we actually do manually with reflection
