import/namespace Correctness
What it does
Enforces names exist at the time they are dereferenced, when imported as a full namespace (i.e. import * as foo from './foo'; foo.bar(); will report if bar is not exported by ./foo.). Will report at the import declaration if there are no exported names found. Also, will report for computed references (i.e. foo["bar"]()). Reports on assignment to a member of an imported namespace.
