using EconML with TensorFlow-2.3.1

[smoors]

the TensorFlow version requirements for EconML-0.8.1 are set to: tensorflow > 1.10, < 2.3

is this a hard requirement?
would it be ok to use TensorFlow-2.3.1 ?

Tensorflows hard version requirements are creating substantially more problems than I think MSFT expected.

We've made a change in version 0.9.0 to move the tensorflow requirement to an extra; tensorflow is only used by our DeepIV estimator, so now if you install just econml there is no tensorflow requirement at all (but you won't be able to use DeepIV), or you can install econml[tf] or econml[all], which will still require tensorflow > 1.10, < 2.3 and enable you to use DeepIV.

Relaxing the dependency is still something we'd like to achieve eventually, but there were breaking changes in keras and tensorflow that make it nontrivial. I'll look into whether a tensorflow < 2.4 requirement would be more achievable than removing the upper bound entirely, which was my previous intention.
