Browser compatibility

Thanks for this great package! :smile:

## Expectation

From `README.md`:

> Compatible with node.js and browsers

## Problem

However, it imports from "util", which is only available in Node JS:

https://github.com/blakeembrey/make-error-cause/blob/629c06daab581559387054fca6edfbb67a6718c6/src/index.ts#L2

And I'm seeing this error in some of my projects:

```
Uncaught TypeError: util_1.inspect is undefined
```

## Reproduction

Here is a very minimal Vite project that demonstrates the problem: [repro.zip](https://github.com/blakeembrey/make-error-cause/files/14614263/repro.zip)

1. `npm install`
2. `npm run build`
```
> vite-starter@0.0.0 build
> vite build

vite v5.1.6 building for production...

3. `npm run preview`
4. Open browser and look in the console to see the error:
Here you can see in the built code where it happened:

## Possible solution

Coming soon ...

Start at src/index.ts, especially the util import referenced in the report, and reproduce the issue with the linked Vite project using npm install, npm run build, and npm run preview. The work is done when the package runs in a browser without the util externalization warning or util_1.inspect error while preserving the README's browser-compatibility claim.
