Readme example of KMC sort has wrong syntax

[jnalanko]

This line does not work:

$ ls -1 --color=no *.fna |xargs -l -i  ~/kmc_tools sort {}_kmc {}_kmc_sorted_kmc.kmc

It returns "Error: Unknow mode: sort". The correct way to do it is:

$ ls -1 --color=no *.fna |xargs -l -i  ~/kmc_tools transform {}_kmc sort {}_kmc_sorted_kmc.kmc
