Reexport.@reexport Module apparently reexports the module name Module itself: simonster/Reexport.jl#39 with no way of avoiding it, which we don't want in the case of ITensors.ITensorMPS. This fixes that with a custom solution using a for loop and @eval.

Without this, if you type using ITensorMPS; using ITensors it results in the following warning:

julia> using ITensorMPS; using ITensors
WARNING: using ITensors.ITensorMPS in module Main conflicts with an existing identifier.
