SQL JSON path enhanced numeric literals

Browse Source 
Add support for non-decimal integer literals and underscores in
numeric literals to SQL JSON path language.  This follows the rules of
ECMAScript, as referred to by the SQL standard.

Internally, all the numeric literal parsing of jsonpath goes through
numeric_in, which already supports all this, so this patch is just a
bit of lexer work and some tests and documentation.
