### What's Done
1. Added a new file named canperformance.c to the project.
2. Modified the Makefile to support the compilation of canperformance.c.
### Core Idea
The addition of canperformance.c aims to meet CAN performance testing needs, compensating for cangen's deficiencies.
### Key Features
- Support for standard and extended frames
- Support for file sending and receiving
- Real - time frame rate display
- MD5 verification for CAN ID, Data, or files
