Integrate test Project.toml into main Project.toml

[pjaap]

Let's see if it runs through

@chmerdon Seems fine now. I think the module is more maintainable if we have only a single Project.toml.
Adding new test dependencies can now easily be done in the [extras] section plus in the [targets] list.

... It is a matter of taste IMHO. I didn't find a reference stating what is preferred by the julia developers.

I personally kind of prefer to have test/Project.toml . Anyway we also have docs/Project.toml.

When I was new to Julia I was always confused by the splitting into test/main Project.toml. I think @chmerdon has to decide here :)

docs is different. For me, docs is an independent project on top of the actual module.

[chmerdon]

is docs really that independent? it runs the same examples, uses all the docstrings... I also find it weird to have then still the docs/Project.toml separately. Can one handle the docs similarly with another target docs?

Technically, docs is a project/environment on its own. You explicitly activate docs in order to create the docs.
Testing, on the other hand, is done out of the main project.

As far as I know, the only valid [targets] are test and build (see Julia Doc).

And I think 2 Project.toml files are still better than 3 separate files :)
