Hi,

The following patches are fairly simple, as this is my first time:

1. Introduced a new general abstraction called `FileOperations`.
2. Implemented `read` and `write` for misc.
3. Updated the sample file for misc.

ManeraKai (3):
  rust: miscdevice: Moved `MiscDevice` to a more general abstraction
  rust: miscdevice: Implemented `read` and `write`
  samples: rust: Updated the example using the Rust MiscDevice
    abstraction
