Bump up the version to prevent deviation between pypi and Github version of pypi (#92)

The pypi 2.3.4 release on pypi contained a test that was not published on github and failed. This caused problems with the conda-forge release of tsam. The version is incremented because the same version cannot be released twice on pypi.
