Extract and summarize batch impact statistics

1	batch_stat(intab, Yv = "conv_area", Cv, BDv, COSTv, Yst, Cst, BDst, COSTst)

`intab`	Impact table from batch run
`Yv`	agricultural impact metric (new land required)
`Cv`	Carbon impact metric
`BDv`	Biodiversity impact metric
`Yst`	Function to calculate impacts across crops (e.g. sum)
`Cst`	Function to calculate impacts across carbon (e.g. sum)
`BDst`	Function to calculate impacts across biodiversity (e.g. mean)
`COSTst`	Function to calculate cost impact (e.g. mean)
`COSTc`	Cost impact metric
