json_parser: number is always converted to float64

What happened?

Description

By default both the standard json library and golang jsoniter library converts number value to float64, there is an option UseNumber from the library, with it enabled, the value will be json.Number and then v.Int64() or v.Float64() returns value in corresponding type or any parse error. It would make sense to honor the original data type from the json parser perspective.

Steps to Reproduce

use json parser to parse a sample json file. f.e. given following log line

{"int": 1, "float": 1.0}

Expected Result

int: int64(1), float: float64(1.0)

Actual Result

int: float64(1), float: float64(1.0)
