[FEATURE REQUEST] Enable passing Headers from a file

[ghecko]

Is your feature request related to a problem? Please describe.
I often encounter frustration when required to specify multiple headers, especially lengthy ones like the Authorization header, directly through the CLI. Updating these headers involves manually removing and re-pasting them each time, which is time-consuming and error-prone. A more efficient approach would allow headers to be passed directly from a file.

Describe the solution you'd like
I’d like the ability to pass headers from a file, with each header specified on a separate line. The tool would read and apply each header listed in the file, simplifying the process of updating or adding headers without requiring direct CLI input for each one.

Describe alternatives you've considered
I've considered no alternative solutions that achieve the same convenience as file-based header loading.

howdy!

it's not exactly what you're asking for, but version 2.11.0 added the ability to scan from a raw http request file e.g. from burp.
