Serializing ubyte[] fails to compile

Attempting to serialize a ubyte[] array results in a compiler error. Line 130 in cereal.d attempts to call dup on length, which isn't an array.

Test Program:

void main() {
    auto test = new ubyte[5];

    auto cerealiser = Cerealiser();
    cerealiser ~= test;

    auto deceralizer = Decerealizer(cerealiser.bytes);
    auto testcpy = deceralizer.value!(ubyte[]);

    assert(test == testcpy);
}

Output
