Configurable scroll container

[josdejong]

See #50

Singleton is not good now, I'l add also something like this:

const jump = function () {
	return jumper().apply(undefined, arguments);
};

export default jump

Using this version of Jump going forward until container support is merged into main.
Came across error when at the top of the page as location() return operator would count 0 as falsy and accept undefined, causing NaN errors. Changed to:

  function location() {
    let top = container.scrollTop || container.scrollY || container.pageYOffset;
    top = typeof top === 'undefined' ? 0 : top;
    return top;
  }

I would love to see this merged.

One potential block is that master was updated to use ESLint a few days after this PR was created. Once merged, ESLint is complaining, but the fixes are simple:

• Add a space after all function names
• Add a space after switch keywords

@callmecavs Are there any plans to merge this and support this feature? Looks like there's quite a bit of interest.

Any reasons to hesitating about merging this PR?
currently using forked version....

Wouldn’t it be better to look up the container going from the target up instead of from the document down?

container = target.closest(options.container)

It would exclude errors where the container selector would be a common class name instead of id. Also might be faster.
