NPM package doesn't include sourcemaps

[lostfictions]

Hi there, I'm trying to upgrade react-simple-maps from an older version, but getting some strange errors. This is pretty frustrating since it looks like there are no sourcemaps bundled in the NPM package, so all I know is vaguely that it's happening in this package somewhere:

Additionally, I have to say that it's pretty frustrating that there doesn't appear to be a changelog, release notes, a migration guide, or even complete documentation of components' props. I'm coming from 0.12 and unfortunately it looks like I'm probably either going to have revert back to that, or drop this package entirely.
