Benchmark should infer schema when running against Parquet

[andygrove]

Is your feature request related to a problem or challenge? Please describe what you are trying to do.
I am trying to run the tpch benchmark against an existing Parquet data set. The decimal type in this data does not match exactly the type hard-coded in the test.

example 1

Failed to map column projection for field l_extendedprice. 
Incompatible data types Decimal128(11, 2) and Decimal128(15, 2)

example 2

Failed to map column projection for field l_extendedprice.
Incompatible data types Float64 and Decimal128(15, 2)
