1. Fix tweedledum runtime detection in BooleanExpression.from_dimacs_file …

   This commit fixes an oversight in the 0.24.0 release that caused an
   accidental change in the exception raised when attempting to use
   BooleanExpression.from_dimacs_file without having tweedledum installed.
   In Qiskit#9754 the detection of tweedledum was updated to avoid import time
   detection so that the module can be imported even if tweedledum isn't
   installed. This was done through the use of the optionals decorators
   so that tweedledum is only attempted to be imported when the
   classicalfunction modules is used. However, the decorators don't wrap
   classmethod constructors by default and this caused the incorrect
   exception type to be raised. This commit fixes this by doing the runtime
   checking manually inside the from_dimacs_file constructor.
