New features
* Added a new "hybrid" solver that exposes an HIGHS/OSQP combinations for large scale
LPs, MILPs, and QPs.
Fixes
Repaired the broken Biomodels Web IO.
Other
Deprecated features
* The OSQP solver is deprecated in favor of the hybrid solver which also uses OSQP but
will not attempt to solve LPs with OSQP anymore. Setting the `model.solver = "osqp"`
will now use the hybrid interface and will raise an error in a future release.
