v2.5.2

• Added the support of CompressionStream and DecompressionStream APIs
• Refactored the code to use the TransformStream API under the hood
• Dropped support of built files for IE11

Warning: The TransformStream API is quite new (especially in Node.js and Firefox), update to 2.5.x if you're sure the environment you are targeting supports it (it can also be polyfilled with https://github.com/MattiasBuelens/web-streams-polyfill by including https://unpkg.com/web-streams-polyfill/dist/polyfill.min.js).
