snap by mode 2
how to snap:
1)create snap group for each vichn,and bind them (not unbind until program end),
that is muti snap group exit, instead of only one
2)create one snap channel for each snap group
3)register snap chn to its corresponding group, snapping, and then unregister
4)repeat 3) to snap muti pictures of the channel
features:
1)need more memory than mode 1, because muti snap group and snap channel exit
2)higher efficiency, because all snap chn run simultaneity.
