Feature request: Allow adding headers to WebpageOptions

[thesurlydev]

In some instances, it's desirable to add custom request headers. Please consider adding headers to the WebpageOptions struct which can then be passed to the Easy handle in HTTP::fetch

Apologies for the delay in response. I agree this is definitely a useful feature.

Adding a new field to the all-pub WebpageOptions is a breaking change unfortunately, but I don't mind moving to a v2 version.
To avoid further backward incompatible additions to the struct we should probably mark it with #[non_exhaustive].

Is this something you would be willing to draft a PR for? I could do it myself but maintenance of this crate is not my top priority to it might take a while.

[thesurlydev]

Sure, I can take a stab at it.

Thanks for the work on this one.
I have just released v2.0.0-alpha.1 so you can use this in your projects.
I'm considering some other breaking changes before I release the official v2
