Don't pad since b3 supports 64-bit as well as 128-bit trace IDs #236

Closed codeboten closed 4 years ago

codeboten commented 4 years ago

This change removes the padding for 64-bit trace IDs as it is no longer needed. In the event of a 128-bit ID that needs to be truncated to 64-bit, the most significant bits will be truncated.
