Bumps flask-cors from 3.0.7 to 3.0.9.

Sourced from flask-cors's releases.

Release 3.0.9

Security

• Escape path before evaluating resource rules (thanks @​praetorian-colby-morgan). Prior to this, flask-cors incorrectly evaluated CORS resource matching before path expansion. E.g. "/api/../foo.txt" would incorrectly match resources for "/api/*" whereas the path actually expands simply to "/foo.txt"

Release 3.0.8

Fixes DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated, and in 3.8 it will stop working

Thank you @​juanmaneo and @​jdevera!
