Update to filesource Move tprev out of the loop to enable storing the previous time value. Add some general warning message that an error might have occurred during reading the time or data values from the data input file. Allow empty lines in the data input file. Guard early data values (TIME < time offset) against false reading. Add some simple examples. 2025-08-11 18:45:21 +02:00			`# simple input, time absolute`
