When '--method best' is used, the output format is not very clear and does not match what is used for ANOSIM and PERMANOVA. This needs to be cleaned up to be easier to read and more consistent with what we already have in place for the other methods.
Additionally, BEST and Moran's I require numeric categories. The error message isn't very clear if a non-numeric category is supplied instead, so an explicit check is needed for this.
