v1.0.0

Changes

• Upgraded almost all dependencies with major versions.
• Changed minifier from UglifyJS to ESBuild, which made compile time go from 4 seconds to less than 100ms (and about same minified file size)
• Removed Underscore dependency, using ES6 or later instead
• Added test (checking if able to build and that output contains expected content)

Breaking changes

• No IE support (in favor of removing Underscore dependency)
• CLI requires NodeJS v14 or higher
