Numeric overflow when formatting Decimal type

[sergiimk]

Describe the bug
When attempting to print out records using arrow::util::pretty::print_batches I get the following panic:

thread 'main' panicked at 'attempt to subtract with overflow', /home/smikhtoniuk/.cargo/registry/src/github.com-1ecc6299db9ec823/arrow-5.2.0/src/array/array_binary.rs:751:50

Schema of the parquet file I'm reading:

message spark_schema {
  required int96 system_time;
  optional int96 event_time;
  optional binary desc (STRING);
  optional int64 delta (DECIMAL(13,4));
}

To Reproduce
I would provide the parquet file, but the dataset has sensitive info. Let me know if you can't reproduce and I'll create fake data.

Expected behavior
Decimal values print out without panics
