Performs an addition of little-endian integers. If the existing value
in the database is not present or shorter than `param`, it is first
extended to the length of `param` with zero bytes. If `param` is
shorter than the existing value in the database, the existing value is
truncated to match the length of `param`. The integers to be added
must be stored in a little-endian representation. They can be signed
in two's complement representation or unsigned. You can add to an integer
at a known offset in the value by prepending the appropriate number of
zero bytes to `param` and padding with zero bytes to match the length
of the value. However, this offset technique requires that you know the
addition will not cause the integer field within the value to overflow.
