Which problem is this PR solving?

Resolves: #2281
Resolves: #2516

• _scrubStatement scrubs all data, including binary data, and with large datasets it can create performance issues.
• Also, it seems it can also end up scrubbing circular references, which can be added by mongoose. (eg: __parentArray)

Short description of the changes

This PR updates the behaviour as described in @trentm's comment.

• Sets a depth limit of 10 for recursion inside deeply nested objects. Please let me know if that needs to be configurable.
• Skips Buffer and Uint8Array data while scrubbing.
• Skips mongoose-added keys, which are marked as non-enumerable from mongoose versions after 5.13.14.

Note: I was not able to test with mongoose versions under 5.13.14 in the unit tests due to type mismatches between [email protected] and mongoose < 5.13.14 devDependencies.
