Sets the four bytes starting at the specified
byteOffset in this
object to the two's complement binary representation of the specified
value, which must fit in four bytes.
In other words,
value must lie
between -231 and 231 - 1, inclusive.
Throws RangeError if
byteOffset is negative, or
byteOffset + 4 is greater than the length of this object.
