load fails when mixing forward and backward slashes on Windows network paths

The error message suggests that the filename is somehow mangled along the way:

julia> load("\\\\132.68.111.72\\sternlab/tmp.png")

A different mangling with more forward slashes:

julia> load("\\\\132.68.111.72/sternlab/tmp.png")

(using FileIO 1.4.4 on Julia 1.5.2)

I can't replicate this because the URL seems interpreted as a filename on Linux.
