Mai2: Add touch and led15070 hook (#55)

In this PR, I have added the `mai2` touch and `led15070` hooks to provide an example for handling custom peripherals. This change allows users to implement the touch and `led15070` logic by writing appropriate `mai2io` scripts.

#### **Touch Hook**:
- The touch hook simulates touch points based on keyboard combinations. For example, to trigger the A1 touch point, the user must press the A and 1 keys on the keyboard. Input for the 1p requires Caps Lock to be off, while 2p requires Caps Lock to be on.
- The hook allows for independent control of whether device simulation is enabled for "1p" and "2p" and whether keyboard input mapping is enabled.
- **Note**: The current touch hook is not yet functional as it requires modifications to the `capnhook` for proper completion of the `sinmai` hook.

#### **LED15070 Hook**:
- This hook implements basic device simulation. Peripherals requiring lighting data should complete the logic as needed.
- **Note**: The LED data refresh can flood the console logs, so I’ve added a `DEBUG` flag to control whether the debug logging is enabled or not.

#### **Other Changes**:
- In certain versions of `sinmai`, key inputs for 1p and 2p can be directly read from the keyboard without requiring simulation via the `amdaemon io4` hook. I’ve added a switch to control this behavior to prevent redundant input.
- **Benefit**: This ensures that key input is only read when `sinmai` is in the foreground.
