Summary: Printing file checksum (usually an integer) in non-hex format is barely useful. To make the matter worse, it can mess with the output format. If you use `less` to redirect the output of `ldb manifest_dump`, non-hex file checksum can cause `less` not to function as expected. Also output some additional fields to json output. Pull Request resolved: https://github.com/facebook/rocksdb/pull/9196 Test Plan: manually test `ldb manifest_dump`.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.
