To Fix ArrayIndexOutOfBoundsException in for VALID_HEX array in OtelEncodingUtils

[NithinU2802]

This PR fixes an issue caused by the VALID_HEX array. If we pass Character.MAX_VALUE, it throws an ArrayIndexOutOfBoundsException instead of returning false, so I updated the size from Character.MAX_VALUE to Character.MAX_VALUE + 1. I believe this is a valid issue, please let me know if any changes are required, I’ll be happy to update it accordingly.
