Get rid of backtracking in jsonpath_scan.l
Non-backtracking flex parsers work faster than backtracking ones. So, this commit gets rid of backtracking in jsonpath_scan.l. That required explicit handling of some cases as well as manual backtracking for some cases. More regression tests for numerics are added. Discussion: https://mail.google.com/mail/u/0?ik=a20b091faa&view=om&permmsgid=msg-f%3A1628425344167939063 Author: John Naylor, Nikita Gluknov, Alexander Korotkov
