img2array not accessible

[Donald Cummins]

Running the code in the maze example I'm getting the following error on both Linux and Windows with Julia 1.10.2.

julia> using Eikonal, Images

julia> σ = Eikonal.img2array(load("maze.png"), ["white"=>1.0, "black"=>Inf])
ERROR: UndefVarError: `img2array` not defined
