[Elphel-support] binning modes, sum and average, how to change them?

[Biel Bestué de Luna]

Oleg
what would be needed to implement pixel binning summing within the php code
like EXPOS, BIN_HOR, BIN_VERT...? Having a boolean parameter to activate
pixel binning summing would be great, and it might not provoke problems
with de-synchronization of states between FPGA and the sensor, and
latencies troubles between FPGA and the sensor as apparently "fpcf -i2cw16
4820 0x60" provokes.

I've been using "fpcf -i2cw16 4820 0x60" since we we're talking about it
some time ago and I've never found any problem, but maybe I was lucky, so
having it solved in the PHP would be great.
