This fixes incompatibility of difficulty calculation between core-rs and the reference implementation (core)
What's in this pull request?
Implements type FixedUnsigned with compile-time scaling. Precision is arbitrary, because BigUint is used internally. Only the number of decimal places is fixed.
Replaces Difficulty implementation to use FixedUnsigned10 (10 decimal places).
Fixes Blockchain::get_next_target to apply the adjustment exactly like the reference implementation using bignumber.js does.
Notes
This will break serialization compatibility
Run cargo bench -p fixed-unsigned to run benchmarks comparing FixedUnsigned to BigDecimal
