Cannot process EGMod

[jwaldmann]

cabal test monadiccp-vuza for 9da3818 gives

Test suite monadiccp-vuza: RUNNING...
monadiccp-vuza: Cannot process EGMod
CallStack (from HasCallStack):
  error, called at src/Control/CP/FD/FD.hs:978:28 in monadiccp-0.7.7-inplace:Control.CP.FD.FD

indeed the Mod operation is missing here: https://github.com/letmaik/monadiccp/blob/master/src/Control/CP/FD/OvertonFD/OvertonFD.hs#L300

for this example, I can work around with c8adfa6

But then, Cannot process EGLess True
