Tried adding webpack (https://github.com/petrbroz/vscode-forge-tools/tree/experiment/webpack) to the project but a couple of 3rd party dependencies (cesium, adm-zip, pug-filters) could not be bundled - those would have to remain in the node_modules folder. Moreover, adding the bundler didn't seem to improve the VSIX file size too much so for now it's probably not worth the effort.
