Could I define the new aggr class directly? [PyG2.2.0]

[StefanIsSmart]

There are some errors happened with the PyG over 2.2.0, just as:
#8959
#8968

What I want to use is the new aggr. class DeepSetsAggregation and SetTransformerAggregation

That point is why I want to update the PyG.

Could I define it directly in my script?

If you don't want to upgrade, you can consider just copy-pasting these files. No guarantees that it works out-of-the-box though.
