Fulcrum 2.0 has been released!

I synced a new DB from scratch, here's my experience:

It took about 2.5 days to sync the new Fulcrum on a laptop (Ryzen 7 5700U, db_mem 8000 GiB).

The v2 DB is a little larger than v1: 176 GiB against 166 GiB.

To test performance, I repeteadly queried a large BTC address (1HckjUpRGcrrRAtFaaCAUaGjsPx9oYmLaZ) for balance and history and got these results:

v1 get_balance: [335, 416] range, avg 378 ms;

v2 get_balance: [348, 355] range, avg 352 ms;

v1 get_history: [32676, 33723] range, avg 33214 ms;

v2 get_history: [23208, 23947] range, avg 23508 ms;

Hopefully someone will come up with better benchmarks, it was a real PITA to measure time due to netcat/socat keeping the connection alive.

Now, the best part:

I left a script running all day, killing -9 Fulcrum and restarting it for a total of 95 kills. The DB was not corrupted.
