Nick Terrell b45d22c851 [contrib][recovery] Add recovery_directory program ...

This program takes a file with concatenated zstd frames and splits the
file up by frame. E.g. if `dir.zst` has 4 frames:

```
> ./recover_directory dir.zst recovery/file
Recovering 4 files...
Recovered recovery/file0
Recovered recovery/file1
Recovered recovery/file2
Recovered recovery/file3
Complete
```
