+MicroW8 loads WebAssembly modules with a maximum size of 256kb. Your module needs to export
 a function `fn upd()` which will be called once per frame.
 After calling `upd` MicroW8 will display the 320x240 8bpp framebuffer located
 at offset 120 in memory with the 32bpp palette located at 0x13000.

 The memory has to be imported as `env` `memory` and has a maximum size of 256kb (4 pages).
