Add Types for nerdamer/all Algebra Extra Solve and Calculus

[JeremyMoeglich]

Type definitions are currently only available for nerdamer core, adding type definitions for the other add-ons would be useful.

This seems like it would make working with the library much easier, both in typescript as well as javascript (because of the autocompletion provided by the types). Why has this been closed?

[JeremyMoeglich]

There is currently a work in progress pull request that rewrites the entire library in typescript.
That should fix the issue, but it seems like that may still take a while.
I don't know if it's worth adding typescript types for the time in between

I may reopen the issue in the future.
