Off-load feature for integrator

Tested the new off-loading feature for the integrator. The attached plot shows two changes in the bias value: the first near 4.5 sec is with the offload button off, the second transition near 8.4 sec is with the offload button on. In both cases the change is reflected on the integrator output value (OUT channel). In the first case, the bias change introduces a transient in the output drive (DRIVE). In the second case, no transient is observed and the integrator value is off-loaded into the bias value smoothly and instantaneously.
