I don't want to license my package, however jsii forces me to or it will not build:

Error: /home/local/ANT/huijbers/Workspaces/CDKAnalytics/src/CDKAmznResources/packages/cdk-amzn-resources/package.json has "license" UNLICENSED, which doesn't appear to be a valid SPDX identifier

• unlicensed or UNLICENSED are not accepted
• The package is marked private: true so I think jsii has no business checking my license at all.
