[issue14366] Supporting lzma compression in zip files

[Martin v. Löwis]

Martin v. Löwis <martin at v.loewis.de> added the comment:

Serhiy, just to be sure we communicated well: I'm not asking that all the missing features for a 6.3 level zip library must be implemented. Instead, we need to detect whether an unsupported feature is used, and raise an exception reporting what the feature is that is unsupported. This is necessary as we otherwise may return incorrect data.
