Browser support via a separate export (Fixes #25)

[samwillis]

This splits the main Ollama class into a base class which supports browser environments, and a subclass for full Node support. Currently the .create() method is only on the subclass.

To use in the browser:

import ollama from "ollama/browser";

Using in Node not changed at all.

It may be possible to also add support for .create() in the browser too but I haven't investigated much yet.

Fixes #25
Fixes #13

Hi @samwillis, thanks for doing this. Do you have any experience with dynamic imports? If possible I'd prefer to use a dynamic import so importing the library looks the same no matter what environment you're in. I'll be taking a look at building dynamic imports on this existing work you have here next week in any case.

Edit: After trying my idea, I now see that this is the correct way to do this.

Thanks for this contribution. Merging this now, and then doing some slight tweaks to allow for creating from the browser also.

[samwillis]

No worries, sorry I didn't get back to you, been a busy week!

@samwillis Could you please expand on the documentation for how to use the browser version? I'm trying to use ollama in a static HTML + JS file setup but the CDN isn't working due to the fs import (see #13).
