PutBits
Places specified amount of bits of value at specified position in packet. To ensure all bits are correctly written, only call this method after bit flush has been performed Parameters pos Position to place the value at, in bits. The entire value must fit in the packet It is advised to obtain the position using bitwpos() function. value Data to write. bitCount Number of bits to store the value on.
