Reads signal data from time stamped ".liio" file using buffered streaming.
The file mask parameter must be the path of an existing .liio file with time stamped signal data, that is readable with the current user's access privileges.
The blocks sample time is always continuous. The signal value only changes, when the simulation time reaches the next time stamp read from file (zero order hold). Width and data type of the output signal of the block are detrermined by the .liio file.
Possible signal types are floating types double and single (in C-terms: float) and the integer data types uint/int of 8, 16, 32, and 64 bits. The signal size can be scalar or a column vector.
