Stop the Labsat_Signal_Source when the end of file is reached. This allows to use this source for automated testing.

Browse Source 
Now the block also accepts directly *.ls2 names in filename parameter

Remove samples parameter, it was not used. This source reads the full file(s).

Make labsat23_source constructor private, so only the smart pointer wrapper can be called
