021-Eurydome

Major changes:

• 20-30x faster syncing (!) thanks to optimizations to the poseidon377 library and parallelization of trial decryption
• added the ability to fetch user transaction data from the chain to the view service using just a provided viewing key (commands to view this data will be coming in the next release!)

Internal changes:

• various optimizations and improvements to the TCT and JMT, including significant optimization of our JMT get function
