Remove unnecessary underscore from impl<T, const N: usize> Distribution<[T; N]> for StandardUniform

[sorairolake]

• Added a CHANGELOG.md entry

Summary

Remove the leading underscore from the _rng parameter of the sample method.

Motivation

Because this parameter appears to be used. I think suppressing the unused_variables lint is unnecessary.

[benjamin-lieser]

This has nothing to do with the removed underscore, because the current master also fails now.
Something has changed with the nightly compiler which breaks our code.

Do you want to investigate this? If not I can do it and would put commits on this branch.

[benjamin-lieser]

So std::simd added their own extract function which gets called instead of our own helper, that why it fails.

Thanks. I agree to fix the broken code and commits it to this branch.

[benjamin-lieser]

I have opened a different pull request for this issue #1586 , if this gets merged, you can rebase and this should then also work.
