Update rage dependency

[besendorf]

Hey,

I wanted to use this library but noticed that the rage dependency was not updated since 0.9.0. As some security issues have been fixed since then I would appreciate if you could update the wasm library to the latest rage version.
I tried myself and received the following errors during build. Build with 0.9.0 worked fine.
