fixes #170
Changes to setup.py to account for the extra package needed for ddg2pca as well as to prevent incompatibilities when installing MutateX from scratch. A compatible version number has been specified for matplotlib, numpy, scipy and adjustText. In the case of adjustText, it has not been checked whether it also causes incompatibility issues when installing, but it's been added as a safety precaution to prevent that other versions of the package cause unexpected problems in the plots.
