This class allows you to override by what means Lanterna detects the size of
the terminal. You can implement this interface and pass it to the 
UnixTerminal constructor in order to use it.

public interface UnixTerminalSizeQuerier {
    
Checks what the size of the terminal is, measured in number of rows and columns. The implementer of this
interface is expected to know which terminal we are querying for and have all it needs to figure out the size.
One way of implementing this could be to read of an external value or variable or calling IPCs or just return
a static size at all times.

Returns:Size of the terminal at this point in time
