Bounds of convexity constraints in master

[hhkramer]

Hello to all.
While implementing the Capacitated Lot-sizing Problem with coluna I noticed that the convexity constraints are imposing a lb of 0 and a ub of 1. Thus, as for this problem I should have lb = ub = 1 in such constraints, the application does not work correctly, resulting in a solution value equal to zero.
I changed the rhs of the lower bound convexity constraint from 0 to 1 in decomposition.jl and it worked.
Having lb = ub = 1 in the convexity constraints is generic for column generation or coluna should have some way to set the sense of the convexity constraint?
Application is available in: https://github.com/hhkramer/ColunaCodes/tree/master/clsp
