@param str String to be parsed
@param strend If non-NULL, set on return to point to the first character
in @a str after those forming the parsed number
@param flags Or'ed-together combination of HTS_PARSE_* flags
@return Converted value of the parsed number.
When @a strend is NULL, a warning will be printed (if hts_verbose is HTS_LOG_WARNING
or more) if there are any trailing characters after the number.
