iota v0.4.0 released

[solidstate1991]

New features:

- GameInput support on Windows, with full support for Xbox 
controllers, including trigger rumble. Dualsense works, but the 
haptics will require a bit more work, due to vibrophonic haptics 
are audio devices, and the adaptive triggers are using 
proprietary protocol.
- Limited evdev support on Linux. Game controllers work, device 
type detection does not work correctly at the moment, as it is 
difficult due to guess work is needed from capabilities.

Also input devices have been moved to numem for memory 
management, this enables new input device detection within 
`@nogc` threads.
