Release v1.8.3.

TL;DR of changes:

• Explicit support for Python 3.7. Earlier compiler versions also worked on 3.7, but now we also run tests in 3.7 to confirm. #148
• Bug fix for compilation error when using has_edge_degree and between filtering in the same scope. #146
• Exposed additional query metadata that describes @recurse and @filter directives encountered in the query. #141
