Fix zip slip security flaw
Apply zip slip checking in zip operations throughout the system. Centralizes most of the zip logic in one class. Create tests to zip functionalities and zip slip problem. Change-Id: I721f3d44b34fe6d242c9537f5a515ce1bb534c9a Issue-ID: SDC-1401 Signed-off-by: andre.schmid <andre.schmid@est.tech>
