Speed up ZLP thickness calculation by binning¶

• added bin control to ZLP IceT settings
• default is bin 1
• can bin up tp 8 on k3
• 8X binning saves ~24s on ice thickness by ZLP for super-resolution images
• only issue is that gain correction does not work if binning is different from exposure binning
• leginon gives a warning
• does not affect calculation, so no reason not to bin
