- Stood up CSD for H1LSCAUX, H1LSC, and H1ECATC1PLC2.
- Updated the xml files for H1LSC and H1ECATC1PLC2 to handle ALS and PRMI states.
- In particular, for the purpose of setting its control state, I split the LSC in four separate systems:
  - The IMC part (H1:LSC-IMC_STATE)
  - The central interferometer part (H1:LSC-PRMI_STATE)
  - The ARMS & ALS part (H1:LSC-ARMS_STATE)
  - The photo diodes (H1:LSC-PD_STATE)
- The xml file easily allows to merge them later or add more / different states.
- The H1:LSC-PRMI_STATE variable currently can be set to PRX, PRY or PRMI
- In addition there is a H1:LSC-PRMI_PD_SELECT variable, which has values of VAC_PD, AIR_PD and 3f_PD.
- In addition I added
  - H1:LSC-MISC_STATE and H1:LSC-PSL_STATE for some additional junk.
  - H1:LSC-MATRIX_LOADING, which punches H1:LSC-PD_DOF_MTRX_LOAD_MATRIX if set to automatic (or does nothing in manual)

One Warning:
 - I spent some time trying to make sure that the H1ECATC1PLC2 does not interfere with guardian or Beckhoff auto-locking. But it is possible that I missed some channels (since there is no channel declaration available in either). So if we have issues tomorrow, we should set H1ECATC1PLC2 into dryop mode and watch for differences.
