ompr.roi 0.7.0.9001

Breaking changes

The package exports column and row duals of LPs. Extracting duals might be solver dependent. Only tested with GLPK. This requires version 0.8 of ompr.
Minimum supported version is 3.4.0 since slam also requires >= 3.4

New features

ompr.roi works with other ompr backends as well.
ompr.roi always returns a solution, even if the solution status is not optimal. It extracts the ROI solution with force=TRUE.

ompr.roi 0.6.1

Bugfix

Fixed a bug where the ROI::V_bound object was incorrectly initialised. This causes an error with ROI >= 0.3.0.
