These changes introduce support for LZ4 compression/decompression into the puffin codebase. Specifically, they expand the Error enum to include LZ4-related errors, modify the file reader and writer to handle LZ4-compressed footers, and update unit tests to ensure the functionality works correctly. The new methods and fields ensure that users can opt for LZ4 compression for file footers, potentially improving both performance and storage efficiency.

In lines of Rust we write, compress, With LZ4, our files caress. Footers now, in this quest, Stored compact, they stand the test. Errors new, tests revised, In puffin's code, we realize. CodeRabbit's joy, in bytes we trust, In LZ4, our data's just.
