Arthur Paulino f56d2f3bad `context.rs` enhancements 
* Improve the phrasing of some docstrings and comments
* Add warning comments about attempts to validate memory addresses
  at reader/writer instantiation time
* Create the `reader_writer` method for ergonomically instantiate
  a reader/writer pair covering the same memory region. This method
  is also slightly more efficient than calling `reader` and `writer`
  separately
* Clean up `check_vaddr` for clarity and rename it to `check_vaddr_lowerbound`
  for explicity
* Include the data length check before calling `check_vaddr_lowerbound`
  in `atomic_load` and `atomic_fetch_update` for further consistency
  with the delayed buffer validation
