[Rust] [Parquet] "min" and "max" written to standard out when writing columns

[asfimport]

For example the following is printed during local execution of a test:

min: [0] 1
max: [1] 1
min: [0] 1
max: [1] 1
min: [0] 1
max: [1] 1
min: [0] 1
max: [1] 1
min: [0] 1
max: [1] 1
min: [0] 1
max: [1] 1

It appears to have been introduced by this PR and was probably vestigial.
