FIGI12 — 8.2.2 add digitial asset details

Add cryptocurrency and digital asset information for clarity;
Currency (fiat, Central Bank Digital Currency or otherwise),Foreign Exchange cryptocurrency, and Foreign Exchange instruments and transactions are neither debt nor equity based and belong in their own category.
Digital Assets, aside from currency and cryptocurrency digital representations, may come in two broad categories .
In the first case, new technologies may be utilized as a mechanism to issue and distribute a cash or derivative instrument, but the resulting financial instrument essentially retains all the same properties as if it were issued through more traditional methods. These may be classified in the same way as any other financial instrument.
In the second case, an existing financial instrument may exist and a digital representation (such as a token) is created as an independent financial instrument unto itself, such that it is derived from the original financial instrument. In this later case, this may be considered a different financial instrument.
