feat: Introduce paginator options

[nervo]

Introduce paginator options, to ease instanciation.

p := paginator.New(
	paginator.WithPerPage(42),
	paginator.WithTotalPages(42),
)

Only these two options has been added, but other could be easily added now that the foundations has been laid :)

Note: to be honnest, i don't know if you prefer such integration, or the "chain" one like:

p := paginator.New().WithPerPage(42).WithTotalPages(42)

I see bof of them in current charmbracelet ecosystem, just tell me :)

LGTM. Thanks for this one and sorry to take so long to get to it, @nervo!

Also, for what it's worth, in terms of initialization, the functional argument style you implemented here is definitely the way to go (versus chaining).

@meowgorithm i've just rebased, do you want me to add other options ?

@nervo I think this looks good. If you think it's ready I'm fine to merge this.

Let's do it \o/
