Pixel clock: get_pixel_clock_range()'s (min, max, increment) describes
a linear range, but IS_PIXELCLOCK_CMD_SET doesn't actually accept
every value in it -- confirmed on hardware, 49/60/73 MHz all failed on
camera 41. Added Camera.get_pixel_clock_list() (IS_PIXELCLOCK_CMD_GET_
NUMBER + _GET_LIST, the SDK's authoritative source for what's settable)
and IDSCamera.get_pixel_clock_list(); IDSCamera.set_pixel_clock() now
snaps to the nearest supported value before writing, instead of
passing the raw requested value straight to the driver.
Auto gain: HW testing found continuous auto-gain has nothing further
to adjust once correctly exposed, and takes gain out of manual
control. on_connected() now pulses auto_gain_enabled on then off
(_AUTO_GAIN_SETTLE_S = 0.5s in between, for the already-running
continuous capture to feed it a few frames), instead of leaving it
enabled like auto_exposure_enabled -- still does the one-time gain
correction, but leaves gain fixed under manual control afterward.
