Lock GRMC with s pol again

Since we have enough green power, we decided to use s-pol again. By changing the gain of GRMC and MZ servo, we could lock both of them again. Also, I changed the integrator of MZ.

We could have 50mW of green light going inside OPO as before.

However, I observed a more stable coherent control 1 loop. This is quite beneficial for the future.
