Hypothesis for Python - version 5.30.1

This patch makes the ghostwriter much more robust when passed unusual
modules.

• improved support for non-resolvable type annotations

• "magic()" can now write "equivalent()" tests

• running "magic()" on modules where some names in "all" are
  undefined skips such names, instead of raising an error

• "magic()" now knows to skip mocks

• improved handling of import-time errors found by the ghostwriter CLI
