Fix JoniRegularExpression compatibility issues with ECMA-262

[justin-tay]

Closes #1192

This fixes the underlying discrepancies in the code ranges for the character classes \d, \D, \w, \W, \s, \S in ECMA-262 vs the mappings to the unicode general categories. As such this also fixes the case where these character classes are used in a character set.

In the process of fixing this it was also noted that \p{digit} is mapping to \d where it should be to \p{Nd} so this was fixed as well.
