PR Summary

• Included a New File Import
  An import for a particular component of the code library named std::io::Read has been added. This provides additional capabilities for input/output operations in the program.

• Optimization of LZ4 Frame Decoder Reading Method
  The method of reading information from the LZ4 frame decoder has been altered. Now it's using read_exact instead of read. This guarantees the full utilization of the output buffer, improving the efficiency and precision of the reading process.
