Faced with the task of adding fit methods to geo-albers-usa-territories , I'm a bit stuck.

Ideally I could follow the pattern found in albersUsa.js, namely

import {fitExtent, fitSize, fitWidth, fitHeight} from "./fit.js";

However, since the projection is not inside this repository, and those internals from fit.js are not exported from the top level of this package, I see no way to access them. Am I missing an approach that would work?

FWIW I did try

import { fitExtent, fitSize, fitWidth, fitHeight } from 'd3-geo/src/fit.js';

But that feels janky, and caused some headaches with Rollup (here's what I tried, for reference).

I propose to export these methods from the d3-geo package, for use by projections defined outside this project.

Thoughts?
