Change up format of requires in the AST
NaNs appear in the AST as '+nan.0' not 'nan.0'
Properly read in 'nan' values from JSON
Higher recursion limit and fake unicode escapes
Fix issue with JSON parser consuming past the end of string literals
This only manifested when the object being parsed had multiple strings
