Lazy evaluations of `get`, and `vget` calls

[germa89]

Some methods returns arrays by default which is convenient but it might be expensive if those arrays are not used.

For instance, vget:

    @wraps(MapdlBase.vget)
    def vget(
        self,
        par: str = "",
        ir: MapdlInt = "",
        tstrt: MapdlFloat = "",
        kcplx: MapdlInt = "",
        **kwargs: KwargDict,
    ) -> NDArray[np.float64]:
        """Wraps VGET"""
        super().vget(par=par, ir=ir, tstrt=tstrt, kcplx=kcplx, **kwargs)
        if not self._store_commands:
            return self.parameters[par]

Ideally we would like to execute the server side call, and then return sort of a "promise" or a lazy evaluated numpy array. The actual values wont be retrieved until the output object is used.
