Prepared PHP training motions v1

Prepared PHP training motions, v1

Five prepared Unitree G1 datasets from the PHP five-teacher training setup: locomotion,
low- and high-speed step, and low- and high-speed climb-76. You can skip motion matching and conversion and train teachers directly from these inputs.

Locomotion	100	118.3 MB
Low-speed step	56	41.8 MB
High-speed step	60	44.8 MB
Low-speed climb-76	40	57.4 MB
