Increase legend color dash thickness?

@kdyrhage

n = 3
plot(rand(10, n), label = "")
plot!(rand(0, n), color_palette = palette(:default)[1:n], linewidth = [3 1 1], label = ["asd" "jkl" "qwe"])

Edit: For anyone wondering for some reason this is not working anymore and creating empty plots to make labels will not work properly
