Neither rate was previously measured anywhere, making it hard to tell a
real acquisition bottleneck from a display/overhead one.
- IDSCamera.get_live_fps() (new USER_ACCESS entry): rolling-buffer
measurement of the live-mode push rate in _live_mode_loop(), readable as
dev.cam_xeye.get_live_fps(). SimIDSCamera inherits it unchanged, so it
works against the simulated deployment too.
- XrayEyeAlign._smear_sweep() now tracks timestamps of the first and most
recent distinct frame it captures, storing the computed rate as
self.last_smear_fps and printing it in the sweep-done summary line.
