pycall api updates

[stevengj]

PyCall 1.90.0 is now released, which change o[:foo] and o["foo"] to o.foo and o."foo", respectively, for python objects o; see also JuliaPy/PyCall.jl#629.

The old getindex methods still work but are deprecated, so you'll want to put out a new release that uses the new methods and REQUIREs PyCall 1.90.0 to avoid having zillions of deprecation messages.

@stevengj a big thank you from the team at the Retriever.ji. This is such a good practice. Is this automated?

[stevengj]

No, I just searched the metadata for packages that require PyCall and manually filed issues with packages that seemed active. It would be nice to have a way to automate this.

@henrykironde I did some quick searching of the current master branch and couldn't find current usage of either the [:foo] notation or getindex. If that seems right to you we can close this. If I've missed something (very possible as I'm just digging in) just point me in the right direction and I'll get these updated.

We do not have this. Thanks for the reminder. I kept this opened to make sure pycall works fine before the release. Thanks @stevengj for this update, saved us some time.
