Detailed Description

An array (contiguous sequence) of a Type subclass elements.

Can be sized (similar to something like the char[10] type in C) or unsized
if no @array_len is given to the constructor (similar to char* used as an
array).

Mapped to MemArray or MemSizedArray, depending on if the Array is
sized or not.

Getting an array field actually returns a MemSizedArray. Setting it is
possible with either a list or a MemSizedArray instance. Examples of
syntax:

    class Example(MemStruct):
        fields = [("array", Array(Num("B"), 4))]

    mystruct = Example(vm, addr)
    mystruct.array[3] = 27
    mystruct.array = [1, 4, 8, 9]
    mystruct.array = MemSizedArray(vm, addr2, Num("B"), 4)
