Helper to create and pass std::istream.
The provided std::istream may either be std::cin, some (gziped) file or an already existing std::istream.
An optional name argument may be passed to the ctor, to identify the stream in log messages, even if it is not a file.
Per default the name is "STDIN", the path to an input file or empty.

Name of the std::istream.
Per default this is "STDIN", the path to an input file or empty. A custom string may be provided to the ctor.
This may be used in log messages to identify the stream even even if it is not a file.

Size of the input stream (informal).
If constructed from an uncompressed file, the file size. Otherwise -1. See setSize;

Set the size of the input stream.
You may set it to whatever vaule is appropriate. E.g. *=10 to compensate gzip compression. or the number of items, lines, ... The value is not used here, just provided.
