fireeth tools check merged-blocks is too verbose by default

I want a mode where it just prints the problems. Don't need all the info by default. Once a problem is found, then go back and print more details.

Checking block holes on /var/lib/dfuse/storage/merged-blocks
Detailed printing requested: All block files will be read and checked for continuity. This may take a while...
