test(render) Campaign FW1: pose-aware oracle trace parser

Browse source 
WalkOracleTrace decodes the P lines of the pose-stamped capture round
(raw IEEE-754 dwords from Render::viewer_pos @0x0081ef00: camera cell,
world origin, the four Frame quaternion components in storage order)
into WalkOraclePose on each frame. Poseless FW0 fixtures parse as
before.
