Fixes #741 When Jest is run with ESM enabled, it passes in either `supportsDynamicImport` or `supportsStaticESM` depending on whether the code is targeting ESM or CJS. The integration now configures Sucrase accordingly, which should be enough for the integration to just work with an ESM Jest configuration.
