Heads up about test error on 1.3

[KristofferC]

When testing this package against the upcoming 1.3 release, the following test error occured:

Error During Test at /root/.julia/packages/KrylovKit/kSkwM/test/linalg.jl:57
  Got exception outside of a @test
  MethodError: no method matching hschur!(::UpperHessenberg{Float32,Array{Float32,2}})
  ...

This is likely due to the PR https://github.com/JuliaLang/julia/pull/31853 introducing the new UpperHessenberg type returned from some functions. Adding a specialization here might be enough to fix it.

Thanks; that's easily fixed but now I run up against a bug in julia master, which I reported in this existing thread:
