scan_jsonescape - parse JSON escaped string
#include <libowfat/textcode.h>
size_t scan_jsonescape(const char *src,char *dest,size_t* destlen);
scan_jsonescape parses JSON escaped text from src into dest, leaving a UTF-8 string in dest. Parsing stops at the 0 terminator, invalid input characters or a double quote that was not escaped.
It will then write the number of bytes in dest into *destlen, and return the number of bytes decoded from src.
dest can be NULL. destlen can be NULL. dest can be src.
To make sure dest is large enough, either allocate strlen(src)+1 bytes or call scan_jsonescape twice, the first time with dest == NULL (*destlen will still be written).
scan_jsonescape returns the number of bytes successfully parsed from src.
