compare a list of headers

[elmarx]

e.g.:

• content-type
• location

Maybe add flag to also compare "security"-headers:

• x-content-type-options
• x-xss-protection
• expires

Or maybe add a type of diff, e.g.:

body-different, header-different, both-different.

Opinion: most headers can be verified easily without shadow-testing, e.g. typically static security-headers.
So only a fraction of headers should be compared, and an additional list could be configured to be compared, too.
