+
+Finds the position of the End of Central Directory (EoCD) signature in the ZIP file. This
+implementation is inspired by that of [async_zip], a Rust library for parsing ZIP files
+asynchronously.
+
+This method involves buffered reading in reverse and reverse linear searching along those buffers 
+for the EoCD signature. As a result of the buffered approach, we reduce individual reads when compared 
+to reading every single byte sequentially, by a factor of the buffer size (4 KB by default). The buffer
+size of 4 KB was arrived at because it aligns with many systems' page sizes, and also provides a
+good balance between read efficiency (not too small), memory usage (not too large) and CPU cache
+performance.
+
+From my primitive benchmarks, this method is ~1.5x faster than the sequential approach.
