Drop python 3.5?

[Florian R. Hölzlwimmer]

Python 3.5 does not support type annotations and format strings.
@Avsecz @MuhammedHasan Should we drop python 3.5 support in the near future or is this still a requirement for some Kipoi models?

I would keep 3.5 for now. Format strings are a nice syntactic sugar, but are not a good enough reason to drop 3.5 support.

I agree with @Avsecz. People still use 3.5 so it will be annoying to drop version.

Yes, but only in parts.
