Reduce number of layouts with three adjacent food pellets

[Debilski]

I thought I had already opened an issue on this topic, but it was with a bad connection, so here it is again: We have a few layouts with three or more food pellets next to each other. I think this is similar to the dead end issue, as they can be quite easily defended even against two attacking bots. We should look at how many layouts have this issue (ex. normal_051) and possibly change the food distribution algorithm.
