Rename `modules` to `components` in `finam.Composition`

Since we always talk about components and use that term consistently in the documentation and the book, I would rename the first argument of the Composition class from modules to `components.

With modules we mostly mean extension modules like finam_netcdf with in turn provide special components.

changed milestone to %v1.0

Ah, I guess it came from the finam submodule finam.modules which provides built-in components.

I guess this should also be named components, but that would have a lot of impact.
