feat!: Use sdk library repo, update eslint and webpack (#67)

    Uses @vertigis/sdk-library package for config files.
    Projects can now customize the webpack settings used when building.
    Fixed issues with webpack when creating a local dev project.
    Upgrade script updates eslint configuration and project type.

BREAKING CHANGE: It is required to run the upgrade script to use this version with an existing project, as a new eslint configuration file needs to be added and the project type needs to be updated to "module"
