Support optional rounding

[CasperEngl]

This PR enables rounding through the roundoption.

round defaults to true and current solutions will continue to behave the same.

When round is set to false, all rounding is disabled.

When round is set to a number, it is used as precision for toFixed.

Fixes #124 and #142

@leerob Is anyone going through PRs on this repo?

[leerob]

Yes, our current focus right now with ms is stability. We have a canary release that publishes ESM and converts to TypeScript: https://github.com/vercel/ms/releases

[CasperEngl]

All right. I'll see if I can change the target branch from master to canary 👍

[leerob]

Those changes have been merged into master (will be main soon), there's just a canary release to test it out first. Main point was we're targeting stability, so likely will be slower to add new features to ms. There are over 100M weekly downloads of ms, so we're extremely cautious about what we add.

Thumbs up on this PR could be a good way to indicate how many people would like to see this feature land 👍

[CasperEngl]

I see. Thank you.

After reviewing this code, I have found nothing wrong with it. It provides the ability to round using any amount and shouldn't cause any problems. I have tested this code multiple times with no error and feel there is no reason the commit not be merged to the main branch.

This works

Current conflicts have been resolved. I've also fixed some issues, having to do with the package name and lock file, since I had been using this package myself, deployed to npm.
