* Name: unpack_package_from_stream
* Description: unpack a package from a stream into a temporary directory
* Arguments: a_idsName - pointer to string representing the input data

* the package to unpack from the specified stream
* a_tempDir - pointer to string representing the path to a
* directory into which the package will be unpacked
* Returns: boolean_t
* == B_TRUE - package successfully unpacked from stream
* == B_FALSE - failed to unpack package from stream
