### Is your feature request related to a problem or challenge? There's room for a lot of optimization. e.g., we currently scan the entire input string multiple times (for trimming and string-based splitting), do various unnecessary heap allocations, use `format!` to produce the result, and re-parse using `i256::from_string` multiple times. For large inputs beyond the target type's scale, we don't need to look at the tail of the string. ### Describe the solution you'd like _No response_ ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
