Error when running KEPTestBP.jl on Preflib instance with altruistic donor

[WPettersson]

Me again :)

Assuming that .wmd/.dat file loading from the branch 16-file-format-description-seems-off is incorporated, I am getting the following error when running julia ../../KEPTestBP.jl 00036-00000011 3 2

 vertex coverage: [1, 0, 1, 1, 1, 1, 0, 0, 0, 1, 0, 0, 1, 0, 1, 1, 2]
- by chain: [17, 1, 17]
ERROR: LoadError: A vertex is covered more than once in the solution

Note that this is preflib instance 00036-00000011 - it has one altruistic donor, and this seems to be causing the issue.

I cannot for sure say whether this is related to #16 or not, as it might be that file reading is not right for altruistic donors isn't right still, or it may be something else in the code.

Sorry but this is holiday for me this week ❄️❄️❄️. I take a look next Monday

Sorry for the delay, I think I fixed this error. When I read the wmd file with new format the matrix containing weights was not filled well. This is definitely linked whith #17
