Hardware interfaces for simulation and deployment

[Chibikuri]

Hardware mock implementation

Background

For testing qrsa components or simulating the entire module, we need mocks for hardware. We also need a clear interface layer for both mock hardware and real hardware.

Implementation Proposal

Use embedded-hal as an interface for mock hardware and real hardware.

Tasks

• [ ] Design interfaces for hardware components (Interface definition should be flexible for future devices)
• [ ] Implement those interfaces on hardware abstraction layer with hal library
• [ ] Tests

[Chibikuri]

Implement hardware interface on real-time controller and mocks in test cases. Various hardware mocks can be implemented as submodules.
