fix(foundation/nsd): Improve nsd import in dependent libraries

[danyill]

Closes #28

One concern with this approach is performance. The nsd.ts is 2.4 Mb.

OTOH it compresses via zip down to 31.7 KiB so transfer time on a client<>server connection with a modern web server should be negligible and I assume that because JSON is a native format it can be efficiently used.

I'm curious about the exact area that performance could be an issue. If I wrap the import of the typescript in a timer, it appears to only be a few ms to load.

I don't currently see how an import data from 'something.js' statement should be significantly more or less performant than a top level const data = await fetch('something.json').then(res => res.json()). @JakobVogelsang in what scenario do you fear a performance degradation?

In general, I'd say that unless an inferred type is really needed for this data, fetching a json file at load time is the cleaner solution, since if we're loading only data and don't need to execute any code, a pure data format is the simpler and safer way to go.

We will rework and try a cleaner solution, thanks for taking a look :+1:
