   Add `ShowBloomFilter` command to parquet-cli. We can leverage it to check 
whether a block can be filtered by bloom filter.
   
   Example usage:
   ```
   parquet-cli bloom-filter -c test_column -v 1226545,3940309
   ```
   
   output
   ```
   Row group 0:
   
--------------------------------------------------------------------------------
   value 1226545 maybe exists.
   value 3940309 NOT exists.
   
   Row group 1:
   
--------------------------------------------------------------------------------
   value 1226545 NOT exists.
   value 3940309 NOT exists.
   ```
