Which package?
intl-messageformat

Describe the bug
In intl-messageformat@9.2.0 intl-format-cache has been replaced with fast-memoize (see mr: 1a7eb02). Unfortunately fast-memoize supports only UMD.

This has introduced an issue for applications that rely on ES6 module syntax (ESM). Because of that the entire application needs to be bundled by Webpack or similar.

To Reproduce
Run the code natively without any transformations or bundling (e.g. es-dev-server can bee used). A WebBrowser will throw:

ReferenceError: module is not defined at node_modules/fast-memoize/src/index.js:140:1

Expected behavior
intl-messageformat is targeted both: Web Browser and node.js. I expect both to work without bundler.
