Assaf Sela 4805fa0eae Remove ldb HexToString method's usage of sscanf
Summary:
Fix hex2String performance issues by removing sscanf dependency.
Also fixed some edge case handling (odd length, bad input).

Test Plan: Created a test file which called old and new implementation, and validated results are the same. I'll paste results in the phabricator diff.
