Claimtrie progress logging.

[moodyjon]

Fixes: #50

I copied claimtrie/logger.go from netsync/blocklogger.go. Copyright comment from there left intact. Let me know if there is a better way to handle derivative works like this.

I did not find a way to handle percentage progress... The pebble stats API stuff seems to be private, so I did not try to use that to estimate the number of records.

Example output:

Though we don't track total number of claims at the moment, this looks like a nice improvement already.

1. Preserving copyright comment is fine.
2. I like how you group changes into logical commits.
3. Another nice to have thing is prefix a category tag in the commit header.
   For example, this can be prefixed with "claimtrie: xxx"
   (I understand not every commits can be categorized cleanly though).
