Upgrade TensorFlow to 2.3.1

[saudet]

Fixes #120

[karllessard]

While this is building, double-checking with you @saudet , did any new generated classes appeared in your source tree after you've build this locally?

[saudet]

No, only the fields in Ops.java get generated in a bit different order for me, but it does that with 2.3.0 as well.

Weird. I thought I'd fixed the generation order. Must be another place that isn't using a LinkedHashMap.
