v8.1.0

Added

• Add Input::input_buffer_publisher() method to provide an RAII-based alternative to the low-level input_buffer()/publish() interface. Thanks @crop2000 !

Changed

• Rename Input::input_buffer() to Input::input_buffer_mut(), keeping a deprecated alias for now, and do the same for Output::output_buffer(). This is the start of a gradual deprecation process whose end goal is to eventually follow the standard Rust accessor naming convention (input_buffer(&self) -> &T, input_buffer_mut(&mut self) -> &mut T, same thing on the output side).
