Add a Python helper script/function to transform point_data objects to met_point_data objects for Python Embedding

[DanielAdriaansen]

Describe the Enhancement

Write a new Python helper script to take a point_data object and transform it to a met_point_data object, to avoid the user having to use ASCII2NC with Python Embedding prior to calling another MET tool.

The workflow would look like this:

1. User Python script is executed that constructs a point_data object
2. User can import functions from this Python helper script to convert point_data to met_point_data
3. The user is returned a met_point_data object which can then be handed off directly to MET tools such as point_stat

This work is a stop-gap to provide users functionality faster than the work described in #2285
