Introduce new classes for binary and integer variables, extending LpVariable. Added related tests to ensure correct behavior, including bounds handling for integer variables.
Previously, LpVariable did not allow specifying an initial value directly. Corresponding test cases have been added to ensure correct functionality.
Updated the variable instantiation to set `varValue` directly in the constructor.

Summary
LpBinaryVariableandLpIntegerVariableclasses to extend functionality.LpVariableduring its creation.fromDataclassto includevarValuefor convenience and clarity during variable instantiation.Motivation
I’ve been working on problems where most variables are binary or integer. It’s a bit annoying having to specify
catfor each one, so I created subclasses to handle this.Along the same lines, I added the option to specify
varValuewhen creating the variable.
