Geosoft redistributables ignore gxpy's user_dir and temp_dir; asks for geosoft.redis file instead.

Context:

• I have written a stand-alone python application that uses gxpy to import a GDB. I am using the latest version of gxpy.
• I use the geosoft redistributables so the user need not have Viewer or Montaj installed.
• I instruct gxpy to use the redistributables through the GXpy constructor: GXpy(redist_override=True, redist_dir="C:/path/to/GeosoftRedist").
• Since user_dir=None and temp_dir=None, gxpy should make its own user and temp directories.

Problem: The redistributable libraries don't actually use the user_dir and temp_dir that gxpy creates. This culiminates in the following fatal error when constructing the GXpy object:

"Error initializing Geosoft redistributable subsystem. Missing: 'C:\path\to\GeosoftRedist\geosoft.redist' configuration file. Contents should include the user and temp directories on two separate lines.

Workaround: I get around this by making my own geosoft.redist file with the required directories. I can confirm that the redistributables definitely read the directories in the redist file: if the directories in the redist file don't exist, then I get another (different) error saying so.

Desired Behaviour: The Geosoft redistributables should not require a geosoft.redist file, and instead use the user_dir and temp_dir generated/provided by gxpy.

@tom-a-horrocks the paths from geosoft.redist will be scanned but will later be overwritten with whatever paths you define or don't define(temp folders) in the GXpy constructor. This is an artifact of the way redist works for other languages (.NET, C#, GXC) where there is no mechanism for specifying these paths and the system has to rely on the geosoft.redist.

As a workaround until a fix can be done, you can create a geosoft.redist file with valid paths. These are used for initialization but will be overwritten with the constructor parameters.
