Currently two identical copies of the archery tradition technology are maintained, one for the Mauryas and one for the Persians. This patch merges them into archery_tradition.json. See attack_steel_working.json and siege_bolt_accuracy.json for comparison.
Furthermore:
- deletes the now empty technologies/mauryas/ folder
- sets the technology in the shared barracks parent, rather than in its individual children (see also final point at D1790), to make it less likely to overlook if another faction (kush?) gets it too
- also adds it to the (as of yet unused) military range
