Zygote w/ nout > 1 and Batch errors

Currently not working. See various commented out tests, e.g.
https://github.com/SciML/Quadrature.jl/blob/2fa4a7d10e213a1206f759310264b411b304e731/test/derivative_tests.jl#L153

@lxvm you said the PR fixed these, did you try the tests? Maybe we can just uncomment them?

[lxvm]

Yes, I uncommented the associated tests in #175. In #191 the additional uncommented tests are for derivatives with respect to boundaries, which are missing for the forward pass, and missing for dim>1 in the reverse pass. I'll take a swing at it in the next week or two

[ChrisRackauckas]

I see, so this can close. I'll mark the others as broken. In general it's just not good to have tests commented out and instead they should be @test_broken anyways, since that will let you know if they unbreak.

Thanks for bearing with me! I'm still learning a lot about best practices for writing packages
