Reads array of integers from given input.

Examples of calls:

// Let l be an integer, v be a vector, and input implement Read.
read_array!([u32, l] from input to v);   // reads l 32-bit integers from input and pushes them to v
v = read_array!([u32, l] from input);    // reads l 32-bit integers from input (as a Vec::<u32>)
v = read_array!([u32, read u8] from input); // reads (from input) number (stored as u8) of elements to read, and read that number of u32 (as a Vec::<u32>)
read_array!(l; bits from input);    // reads l (rounded up to a multiple of 64) bits from input as a Vec::<u64>
