"Unexpected token ." errors from ?. operator on modern runtimes

[TJC]

I wondered if anyone else is seeing client-side errors coming in related to the ?. operator at https://github.com/ulid/javascript/blob/master/source/ulid.ts#L51

It manifests as Unexpected token . with the stack trace pointing to node_modules/ulid/dist/browser/index.js:158 -- which holds:

if (typeof globalCrypto?.getRandomValues === "function") {

Our error-tracking reports modern browser versions, where the ?. operator has existed for many years.

Since I'm at a bit of a loss here, I thought I'd create an issue here in case others are seeing this. Maybe we can work something out?

ulid versions we've seen the issue on: 3.0.0 and 3.0.2
