Update text spotting and tests with new package names

[rwood-97]

Summary

As of 18/10/2024, I updated the code for MapTextPipeline, DeepSolo and DPText-DETR so they all have their own namespaces.
This PR updates the MapReader code to reflect these changes.

Ultimiately this makes it possible to install all three text spotters at the same time!
