Detect Navigation Type of geocat file

[joleenf]

This pull request adds checks for global attributes in the geocat file to determine if the navigation has been terrain corrected. If it has, a SwathDefinition is used to facilitate the irregular grid of coordinates.

The yaml was also updated to separate level1 from level2 file_types.

A check for projection_longitude was also added since this appears to be in the global attributes now.

• Closes Detect Navigation Type in GEOCAT files #2512
• Tests added to check if the terrain corrected property is set to true when there is indication of terrain correction in the global attributes
