Feature/nilesxug/overature data

[nilesxug]

Description

Adding the overature data to the training data runner so that they are pulled into the training data. The overature data is currently weighed by microsoft_v8_volume and ghsl_r2023a_volume features. We can expand that to other features in the future.

Checklist

• Tests covering the new functionality have been added: Not yet, will add the test once we have the full distance rasters
• Documentation has been updated OR the change is too minor to be documented: Given these changes do not affect functionality, no need to update documentation
• Changes are listed in the CHANGELOG.md OR changes are insignificant: I didn't see anything in the CHANGELOG.md file so I assume changes are monitored elsewhere?
