function infinitemps_approx, converting finite mps to iMPS appears to be broken

[HumpyBlumpy]

Hello,

Thanks for the great package!
I understand that it is work in progress, but I came across the function infinitemps_approx and I am trying to understand how it works in order to incorporate it in my code.
I tried running finite_mps_to_infinite_mps.jl from the examples folder, but it gives an error ERROR: v₁ᴿᴺ not hermitian after the call to orthogonalize. Perhaps there is a easy fix to make it work again?

Thanks
