Add ESM exports and split dependencies

[mentaljam]

Hi!

Thank you for maintaining this great project. While integrating it into our Next.js app, I encountered an error related to an undefined Worker. After investigating, I found that the issue was resolved when using the "unbundled" version of maplibre-cog-protocol.

This pull request introduces a patch that provides an ESM build of the package. The build excludes bundled dependencies, and I’ve separated them into devDependencies, peerDependencies, and dependencies.

Additionally, the existing UMD bundle remains unchanged to preserve backward compatibility.

I got this error, thanks

I've done some local testing with the PR suggested above and it also appears to resolve the problems I was having with reference to "Worker".

In addition I'm using [email protected] and the library appears to work fine, except if the peer dependency is referring to v4 then there is a problem of mismatching types (due to the parameters that are passed to the protocol).

Would be great if the library could be updated with this PR and enabling maplibre v5 as a peer dependency!

Otherwise excellent library, definitely solves some problems for me.

(p.s. my guess is that the above screenshotted error is related to client/server components in next, and not to the changes proposed)
