Start working on fixing interpolation for fixed edisp

[maxnoe]

@RuneDominik This is a PR targeting #250 with changes related to the interpolation code.

I started this during ICRC and will have a look now again, I don't remember quite how far I got, please have a look and maybe just push here any changes you might want to include to make it work
