Use curl_easy_option_by_id to retrieve the name of the option, and also show the name of the option in the case where strings contain a null byte.

curl_easy_option_by_id simplifies the code, but was introduced in curl 7.73.0, so this also bumps the minimum version of curl. 7.73.0 was released in 2020, so I think that's acceptable.

Showing the option name is especially useful when using curl_setopt_array. A user may specify many options, and this change makes it clear which option is wrong exactly.
