Pull Request Overview

This PR fixes an index incrementing bug in string parsing for OSC (Open Sound Control) packets. The issue was that the string parsing method didn't correctly advance the index after reading a string, leading to parsing errors.

• Modified GetString method to return the new index position via an out parameter
• Updated string and symbol parsing logic to use the corrected index advancement
• Added comprehensive test coverage for string padding scenarios
