Import external packages under symbol

[light-matters]

Currently, importing an external Wolfram package works but the new symbols are not, by nature, accessible from wolframite.wolfram (and so have to be executed using the deferred forms).

We could provide a library method for adding external packages seamlessly.

The two main options would be to either

1. use clj-intern (as I used previously on the realatoms project).
2. somehow update wolframite.wolfram or create a similar namespace file (that is accessible at runtime).

wolframite.impl.wolfram-syms.write-ns/write-ns! could be perhaps hacked for this purpose but it may be cleaner with a dedicated fn. A question is whether users would want one ns file per package or a single one. Given namespacing needs, the former may be preferable?

Perhaps there could be a variant of load-package! which also writes (and loads) this ns...

A dedicated function would probably be best and I think 1 per package would be the cleanest, though Wolfram is somewhat weird about namespaces. A variant of load-package! would be great; manually writing lots of namespaces would, of course, be a pain.
