Merge #15751: Speed up deriveaddresses for large ranges
41a46cbb31f1622f7d1ff54c7a1c1ca701c1e754 Speed up deriveaddresses for large ranges (Pieter Wuille)
Pull request description:
`deriveaddresses` dumps all generated addresses into a single `FlatSigningProvider`, which is also used for looking up information for future derivations. @achow101 points out that the growing data structures may unnecessary increase lookup time for later derivations.
Fix this by separating the provider used for lookups (`key_provider`) and the one we dump things into.
This gives a 10x speedup for a range of 7000 elements, and probably a larger speedup for larger ranges.
