Submodules in one file should be indented according to BlueStyle

From: https://github.com/invenia/BlueStyle#modules

Sometimes, e.g. for tests, or for namespacing a enumeration, it is desirable to declare a submodule midway through a file.
In this case the code within the submodule should be indented.

Consider the following code:

module Foo
module Bar
    x = 2
    y = 4
end

z = 5

end

It is correctly formatted by BlueStyle.

But after I run JuliaFormatter it ends up wrong:

julia> format_text(str, BlueStyle()) |> println
module Foo
module Bar
x = 2
y = 4
end

z = 5
end

Is this recursive? what would this be

module Foo
module Bar
    x = 2
    y = 4
    module C
        stuff
    end
end

z = 5

end

That would be unchanged.

Basically the rule is:
Indent within modules, unless that module is the first/outermost module in this file.
