Large numbers in pretty printing

This is not helpful:

>>> let sun_luminosity = 3.828e26 W

  let sun_luminosity = 382800000000000000000000000 watt

Also: let's look into formatting large (integer) numbers with spaces as separators. Qalculate does this, and I think it's quite neat:

I think it would be better to use underscore so we can copy-paste it back in numbat if possible 🥺

For the web version, I believe that there might be a way to show a space, but to leave the actual content as "123456789".

Maybe we could even make this work for the CLI version if we use a special space character, like a non-breaking space (U+00A0).

Then it would be nice to accept the non-breaking-space as a valid character in the cli because they will get copy-pasted.
If we do that, it could actually work in the web version as well, I guess? 🤔

Yes, exactly. We could treat the non-breaking space similar to how we treat the underscore.. I assume

True, yes

Decided to go with an underscore for now, as this non-breaking space caused some problems when copy pasting.
