I'll temporarily place an upper bound on `diagrams-lib`

Read the diagrams-lib-1.6 and diagrams-solve-0.1.3.1 changelogs, then inspect the Stackage package entries for each listed dependent and their version bounds. Done means the package set no longer rejects the released versions, with the temporary diagrams-lib upper bound handled and validation passing.
