Update header file naming and improve backward compatibility

- Renamed canonical header from slick/stream_buffer_multiplexer.h to slick/stream_buffer_multiplexer.hpp.
- Added backward-compatibility shim in the old header to direct users to update their includes.
- Updated CMakeLists.txt to reflect the new version 1.0.1 and dependency changes.
- Modified README and test files to use the new header file name.
- Documented changes in CHANGELOG.md.
