In order to avoid stack overflows for deep value trees, internal recursive calls have been replaced with loops, including for the destructor on Hjson::Value. As a side effect the Hjson::Value desctructor will now allocate memory on the heap if the Hjson::Value is a tree with a depth greater than two levels.

Backported fix for gcc 13 requiring cstdint to be included in hjson.h.

• Added override specifier in hjson.h to avoid possible compiler warning
• Fix for warnings about name collision during link time optimization

Any control chars in map keys are now escaped in Hjson and JSON output.

Now includes <cstdint> in the file hjson.h which is required by GCC 13.

Fixes problems with values and/or closing brackets ending up inside comments, even when the tree was unmarshalled from a document.

It is still possible to get this problem when programmatically setting comments.

If DecoderOptions::whitespaceAsComments is set to true, comments now also include trailing whitespace after quoteless strings.

Changed behavior:

• UnmarshalFromFile() will now ignore the last line feed in a file if the file ends with a comment. Before this change, a read-write cycle of a file with comments would always add one more line feed at the end of the file if the file ended with a comment.
• The output from Merge() of two maps now uses the key order from the second Hjson::Value argument because the second argument is typically from an input file written by a user, and we don't want to keep changing the order that the user had decided.

Bug fixes:

• Lower (second level or deeper) level maps now keep their comments in the output from Merge().
• Value::clone() now keep all comments.

Added Hjson::Value bracket operators for non-const char* to avoid overload ambiguity.

Major release containing several breaking changes.

Biggest change: can now read and write comments.

• enum class for Hjson::Value types
• changed default options
• assignment and arithmetic operators for all primitive C++ types
• read and write comments
• convenience file functions
• MarshalWithOptions() replaced by Marshal() overload
• DefaultOptions() replaced by brace-or-equal-initializers in EncoderOptions
