import can do this, basically it gives you an array that you can
cast to ubyte[] for binary too, be careful with enums though,
because enum arrays will allocate every time you access it
string data = import("strings.txt");

However for security reasons it only looks in folders which you
pass with -J flag
or with dub using "stringImportPaths"
