v0.1.0

Initial release.

This does not have feature parity with akarin.Expr or llvmexpr.Expr quite yet:

• Accessing frame properties is currently unsupported.
• Some operators available in other plugins may still be missing here.
• The implementation of stack manipulators (drop, dup, and swap) currently differs from other Expr implementations. This may lead to behavioral differences in complex expressions. This will need to be overhauled in a future release.

Despite all that, the plugin is in a good enough state for testing and experimentation.
