Can you please help me to understand the use-case? Looks interesting...

Thanks @elek for the interest in this work. As we know, with prefix based
implementation keypath stores only leaf node(fileName/dirName)i and table key
like <parentID/fileName>. The idea behind this tool is to print only necessary
information to quickly help to inter-connect the path elements. `ldb` is
printing entire details and which is difficult to go through all the content
and find out any mistakes quickly. I believe, we would add more tools based on
the usability/debugability.
Welcome thoughts/feedback:-)
```
For example, if a key "a/b/key1" created into a FSOBucket then each
path component will be assigned an ObjectId and linked to its parent path
component using parent's objectID.
Say, Bucket's ObjectID = 512, which is the parent for its immediate child
element.
| ------------------------------------------|
| PathComponent | ObjectID | ParentID |
| ------------------------------------------|
| a | 1024 | 512 |
| ------------------------------------------|
| b | 1025 | 1024 |
| ------------------------------------------|
| key1 | 1026 | 1025 |
| ------------------------------------------|
