Use BufRead for JSON Schema Inference

[WenyXu]

Which issue does this PR close?

Rationale for this change

Enhance API flexibility.

In our use case, we have a SyncIoBridge which implements the Read and BufRead traits, and it works well with arrow::csv::reader::infer_reader_schema.

        let reader = SyncIoBridge::new(decoded);

        let (schema, _records_read) = arrow::csv::reader::infer_reader_schema(
            reader,
            self.delimiter,
            self.schema_infer_max_record,
            self.has_header,
        )

However, the ValueIter::new only accepts the type of BufReader<Reader> argument. If changing BufReader<Read> to BufRead, We can call the API without the BufReader wrapped outside.

        let mut reader = BufReader::new(SyncIoBridge::new(decoded));
        let iter = ValueIter::new(&mut reader, self.schema_infer_max_record);

Where did you see the clippy error? It was not detected by CI.

Looks okay to me.
