Subject: Update IO::Buffer#get_value benchmark

- The method was renamed from `get` to `get_value`
- Comparing to `String#unpack` isn't quite equivalent, `unpack1` is closer.
- Use frozen_string_literal to avoid allocating a format string every time.
- Use `N` format which is equivalent to `:U32` (`uint_32_t` big-endian).
- Disable experimental warnings to not mess up the output.
