Run FBA tests on all BiGG models

FBA simulations with all BiGG models should be performed and compared against reference solutions from cobrapy.
BiGG models are not part of the repository, but must be downloaded for testing in CI or locally. Access is via environment variable.

Most of this is implemented in
shalinshah1993@cefc069

This issue depends on #24, i.e. only if FBA is working than it can be run on all BiGG models.

Now, all FBA tests of BiGG models are running and passing successfully, so should I link this issue to PR #54 so that it can be closed on PR merge?
