expression: support Expression init with constant values (pandas, numpy, scalar) #242

It is now possible to create LinearExpression from a pandas.DataFrame, pandas.Series, a numpy.array or constant scalar values, e.g. linopy.LinearExpression(df). This will create a LinearExpression with constants only and the coordinates of the DataFrame, Series or array as dimensions.
