Fix bug in MSPFormat reader

[odow]

Closes #637

I didn't test, but it seems like this is the likely culprit.

@bonnkleiford You can install this branch with:

] add SDDP#od/fix-msp-format

[odow]

Seemed to work so I'm going to merge:

julia> using SDDP
[ Info: Precompiling SDDP [f4570300-c277-11e8-125c-4912f86ce65d]

julia> m = SDDP.MSPFormat.read_from_file("/Users/Oscar/Downloads/Energy/Energy")

A policy graph with 22602 nodes.
 Node indices: 5461, ..., 5734

Now you just need to install the latest version:

] add SDDP#master

If you confirm that this fixes the problem, I'll tag a new release.

HI Oscar,

I tried it and reading the problem (model and lattice JSON files) works but it cannot solve it. It still gives out the same error message: [image: Screenshot 2023-07-09 at 14.41.26.png]

Thanks again for the help.

Also, I tried it with the rest of the synthetic problems and so far, I got a new error on one of them:

Hi Oscar,

For the Energy Problem, I still got the same error message:

The issue was not on reading the problem (JSON files) but when SDDP.jl solves it, then I get the error message above.

For the other problem (Hydro_Simple), I got this error message when I read the JSON files:

Here are the files for reproduction: Hydro_Simple.zip

Thanks!

For the energy problem, I don't think you updated your version of SDDP.
