vCO - convert decimal net mask to decimal octet

I had to calculate the dotted subnet mask from normal formatted network string like:

192.168.12.0/23 --> 255.255.254.0

In vCO pow(x,y) is not available, so I had to build an action which transform the decimal part (here 23) into a dotted format by using a function to calculate pow(2,x).
Because the decimal part was got by .split("/") the input parameter is also string. You an easily rewrite this action for number input usage.
