Puts an array of bytes into this byte vector. The byte vector is automatically enlarged if
necessary.

@param byteArrayValue an array of bytes. May be {@literal null} to put {@code byteLength} null
bytes into this byte vector.
@param byteOffset index of the first byte of byteArrayValue that must be copied.
@param byteLength number of bytes of byteArrayValue that must be copied.
@return this byte vector.
