Remove #import directive (#389)

Fixes #380

The `#import` directive was a stopgap measure to allow a macro-heavy shader library to incrementally adopt `import`, but it has turned out to cause as many problems as it fixes (not least because users have never been able to form a good mental model around which kind of import to do when).

This change yanks support for the feature.
