Returns the first valid (long) integer number from the serial buffer. Characters that are not integers (or the minus sign) are skipped.
Initial characters that are not digits or a minus sign, are skipped;
Parsing stops when no characters have been read for a configurable time-out value, or a non-digit is read;
If no valid digits were read when the time-out (see Stream.setTimeout()) occurs, 0 is returned;
