The Extended Supported Rates Information Element
This class knows how to serialise and deserialise the Extended Supported Rates Element that holds (non-HT) rates beyond the 8 that the original Supported Rates element can carry.
The SupportedRates class still records all the rates, and an instance of ExtendedSupportedRatesIE lies within SupportedRates.

This information element is a bit special in that it is only included if there are more than 8 rates.
To support this we override the Serialize and GetSerializedSize methods of WifiInformationElement.

This member points to the SupportedRates object that contains the actual rate details.
This class is a friend of that, so we have access to all the private data we need.
