 APIS Codes for GWR Class 150, 158 & 16x units

+Re-initialised in a new repository on 04/12/2025.  This decision was made to keep one data type, in one repository to maintain separation of data-ingress services in preparation for the 2026 data-ingress project.
+
+Data is prepared for the data-ingress service using Gitea actions, any changes made to the actions require care to ensure it doesn't break the ingress of data to OwlBoard.
+
+## Making Changes
+
+Updates should be made in a branch following the naming pattern:
+
+```
+branches:
+- auto-*
+- pis-*
+```
+
+Updated should be placed in to a new file in the /pis/ directory.
+
+Code deletions must be made in the 'main' branch.
+
+
+## Future Considerations
+
+Adding traction type field to cover 80x generic headcodes, and whatever 175's use if not the same as other units.
