GH-3125: Add CLI for SizeStatistics

[wgtmac]

Rationale for this change

There is no way to print size stats from the parquet-cli yet.

What changes are included in this PR?

Add a new CLI command for SizeStatistics.

Are these changes tested?

Added a test case.

parquet-cli size-stats

File with both histogram and unencoded bytes.

Row group 0
--------------------------------------------------------------------------------
column unencoded bytes rep level histogram def level histogram
[int32_field] - [10] [10]
[int64_field] - [10] [10]
[float_field] - [10] [10]
[double_field] - [10] [10]
[binary_field] 46 B [10] [10]
[flba_field] - [10] [10]
[date_field] - [10] [10]

File with only unencoded bytes.
