[Bug] `monero-blockchain-prune` copies the whole DB. Extremely slowly.
Initially setting up the node in the GUI wallet a long time ago I picked the pruned option.
The CLI option for pruning was not added but I assumed a DB seeded as pruned wouldn't be able to grow to the full ledger size. I was wrong.

Ran the daemon ever since without the pruning CLI option until it gradually reached 172 GB, which seems like the size of the full ledger. Added the CLI option and ran like that recently.

There was some option to check if it's pruned in `monerod` itself, IIRC, which reported it as pruned.

However, pruning with `monerod` does not reduce the file size, as it only marks entries available for overwriting. I wanted to deflate the database by discarding the marked entries from disk. And that's what `monero-blockchain-prune` is supposedly for.

Running `monero-blockchain-prune` prints `Blockchain is already pruned, use --copy-pruned-database to copy it anyway`. So I added that option.

```

I don't believe pruning was supposed to slightly increase the size of the database.
By golly, this is the most inefficient file copier I have ever ran, taking three days to copy a 172 GB file.

P.S.
At the point where it rapidly shot past the expected size, it started using all of the available memory on Windows 10 on the file handle of the initial DB — probably a read cache/buffer.
