Update To New Version Of Intre Map Optimization

[philip-paul-mueller]

In the previous version of the new intra Map optimization scheme TaskletFusion was on by default.
However, this was changed to combat negative behaviour in the dycore, i.e. there is now a switch and it is disabled by default.
This PR updates the feature to the newest version and also enables it for graupel by default.
