benchmarks/src/bin/tpch.rs is failing to convert TPC-H's tbl file to parquet
file.
because there's a tailing '|' in the tbl file like this:
```
1|goldenrod lavender spring chocolate lace|Manufacturer#1|Brand#13|PROMO
BURNISHED COPPER|7|JUMBO PKG|901.00|ly. slyly ironi|
```
So Arrow believes the schema doesn't match CSV itself and throws `Error:
ArrowError(CsvError("incorrect number of fields for line 1, expected 9 got more
than 9"))`
