 * @brief Initialize JSON parser
 *
 * This function creates an object \ref fmt_t which must be freed
 * with \ref fmt_free().
 *
 * @param  p     pointer to \ref fmt_t structure to be used as parser
 * @param  size  parser configuration
 *             - initial token count parser will be able to process
 *               without excess memory reallocation. If defined token count
 *               is not enough to parse json string/file more tokens
 *               will be allocated dynamically. One may want to use 0
 *               to optimize memory usage.
 *
 * @return LIBFMT_ERR_NONE on success, negative error code otherwise
