fix: non browser environment compatibility which breaks SSR compilation

[khelkun]

Hello @yoannmoinet ,

To make the story as short as possible:

• super.js has global access to the global window object which only exists in a web browser environment.
• I use nextjs, which uses SSR component (server side rendered component).
• SSR component doesn't need nipplejs, but it imports client side components which use nipplejs.
• That means SSR compilation imports the nipplejs module no matter it really uses it server side or not.
• So the SSR compilation fails because the window object in super.js is accessed at the nipplejs module import, and also because on top of that the nipplejs library itself is built as umd but without defining globalObject in webpack config for the compatibility on non browser environments.

For the record, the error is:

ReferenceError: window is not defined

So this PR has 2 commits:

• one to prevent accessing window object globally during the super.js module import
• another to define globalObject in non browser environment and throw an error if nipplejs Manager.create is actually called from a non browser environment.

If you could accept that and release a nipplejs version toward it, I'd be really grateful 🙏

N.B: I first tried to mock the nipplejs module resolution during SSR compilation using the webpack config of nextjs config. But I did not find a config that fix the issue. Apparently because the nodejs resolve the modules earlier but I'm not sure about that...

Thanks for the very well detailed PR, really appreciated.
I'll have a look asap.

I'm wondering if we'd still have the issue with the massive v1 rewrite I'm currently doing in #221
Given that I'm now bundling the code differently.
