flask session cache handler in 2.20.0

[gabylorenzi]

code i am running
python3 auth-test.py (a renamed version of app.py from the 2.20.0 version of spotipy)

environment:
python3
pip3
spotipy=2.20.0

error message:
`python3 auth-test.py

I can see that there is a newly added flask session cache handler in the version 2.20.0, but despite having the latest version of spottily installed, i am getting an error. would love any help! thanks in advance!

I need to release 2.21.0 for it to be available. For now you can use master or a specific commit.

would love to use this with flask as well.
