ZIP - inflating and deflating strings and files using zlib and minizip

This XOP is able to inflate and deflate strings and unzip zip archives.

The deflation and inflation of strings is encoded in .z and .gz formats. You can use this to compress strings (or any other data) inside IGOR. By using fbinread you can also zip individual files.

You can also unzip zip archives that contain multiple files.

ZIP is based on the free zlib library (www.zlib.net) and the Minizip code by Gilles Vollant (http://www.winimage.com/zLibDll/minizip.html)

This can be useful for zipping and unzipping waves using the SOCKIT.xop. (This has commands SOCKITstringtoWave and SOCKITwavetostring).

To unzip zip archives use the following code:

The /O flag means that files extracted from the sourceZipfile will overwrite those already contained in the outputDirectory.
outputDirStr is a string containing the directory location for the extracted files.
sourceZipfileStr is a string containing the location of the zip archive.
Both outputDirStr and sourceZipfileStr must be native file paths, i.e. NOT POSIX.
In addition, all directory structure from the zip file will be lost/flattened.
