We do so by tracking the imports on exist of each scopestack; and on exist, if there is an import that has not been checked; we mark it as unused.
This seem to have side effects as the SourceToSource transformer is aware it cannot remove non-global imports and emit a error message.
Note that this also affects conditional imports:
The first import will be marked as unused as shoadowed by the second one (pyflyby does not understand the if/else).
This also does some refactor and type anotations while I am at it.
