Progress reporting for streaming files from Mac OS ZIPs

[overlookmotel]

Users can easily get progress of streaming files from a ZIP by counting bytes on the stream returned by openReadStream() and calculating as proportion of entry.uncompressedSize.

Problem is Mac OS ZIP files where entry.uncompressedSize can be inaccurate. In this case, would need to calculate progress prior to decompression as a proportion of entry.compressedSize (which is accurate).

This cannot be performed externally and would need some kind of "hook" within yauzl-promise.
