Riecoin 0.21.0

The Riecoin code has been ported to Bitcoin 0.21. More details on the Riecoin Forum. https://forum.riecoin.dev/viewtopic.php?f=6&t=33

There are interesting changes from Bitcoin like the Taproot/Schnorr Signatures Code or Descriptor Wallets feature. The Taproot Softfork is already activated on Testnet, and the activation process on Mainnet will start on May 1, activating if 75% of new blocks signal support (Bip9 activation). It will unconditionally activated around July 1 if the Bip9 activation fails. To signal support, just mine using 0.21, or on a pool that upgraded.

Other Riecoin specific changes from 0.20 are that a Default Fallback Fee is now provided (which suppresses a very annoying Error Message when sending coins), and the Mining Power metric after the Fork is fixed (it mistakenly still used the previous Minimum Difficulty as a reference). Some small code refactoring was also done.
