Namespaces
namespace	daw
namespace	daw::json
	string_writer grows its string with resize_and_overwrite, leaving the new bytes uninitialized, when the standard library has it. That skips zero filling memory that is overwritten right away, but the bytes past what was written are never initialized, which resize_and_overwrite's precondition does not allow. Define DAW_JSON_NO_LESS_SAFE_STRING_WRITER to grow with resize( ) instead

Macros
#define	daw_json_assert_weak(Bool, ...)
	Assert that Bool is true when in Checked Input mode If false pass rest of args to daw_json_error.
#define	daw_json_dbg_ensure(Bool, ...)
#define	daw_json_ensure(Bool, ...)
	Ensure that Bool is true. If false pass rest of args to daw_json_error.
