In biggis-project/soh: Hotspot analysis and stability metrics

Getis-Ord G* statistics using a weight matrix. Data on the border are padded with the mean value during convolution.

1	GetisOrd(r, w, st = GetisOrdStandardStats(r))

`r`	Input raster
`w`	Square weight matrix with odd number of rows/columns.
`st`	Expecting a list of local statistics, see GetisOrdStandardStats and GetisOrdLocalStats

New raster of the same size as the original input raster r.

library(raster)
r <- raster(matrix(rnorm(400), 20))
w <- weight_matrix_circular_fade(7, 2)
plot(GetisOrd(r, w))
