can't use slic-watch-core without a bundler

[James Kyburz]

Describe the bug

I was going to start writing a sam plugin for this for sam-expand however found that slic-watch-core couldn't be imported or required. This is because the file is .js, the module isn't type module, and there aren't any package.json exports.

slic-watch-core doesn't work with require or import.

To Reproduce
Steps to reproduce the behavior:

~ ᐅ nvm use 20
Now using node v20.11.0 (npm v10.2.3)
~ ᐅ mkdir -p /tmp/slic-test
~ ᐅ ^mkdir -p^cd
~ ᐅ cd /tmp/slic-test
/tmp/slic-test ᐅ npm init -y &>/dev/null && npm i slic-watch-core &>/dev/null
/tmp/slic-test ᐅ node
Welcome to Node.js v20.11.0.
Type ".help" for more information.
> require('slic-watch-core')
/private/tmp/slic-test/node_modules/slic-watch-core/dist/index.js:27
import { get, merge } from "lodash";
^^^^^^

Uncaught:
SyntaxError: Cannot use import statement inside the Node.js REPL, alternatively use dynamic import:
> import('slic-watch-core')
Promise {
  <pending>,
  [Symbol(async_id_symbol)]: 141,
  [Symbol(trigger_async_id_symbol)]: 6
}

Environment:

Thanks for this @JamesKyburz. It makes sense from a first look. We are planning on a separate, library version of slic-watch-core so this is good to know about. We are just going to test all permutations of the PR before merge and release.
