Add 'column-size' command to parquet-cli and parquet-tools #1587

To determine which column to be removed when running the 'prune' command, one of the factors is to check the size of each column. This Jira is to add a command to get the size in both bytes and the percentage of each column. It can be considered as the width of each column.
