[elidana]

update model name for Guralp sensors.

• CMG-3ESP-Z to CMG-3ESP/Z
• CMG-3TB-GN to CMG-3TB/GN
• CMG-40T-30S to CMG-40T/30S
• CMG-40T-60S to CMG-40T/60S

Should now align with models listed in the IRIS Nominal Response Library https://ds.iris.edu/ds/nrl/sensor/guralp/

This looks good, we'll need to co-ordinate once this is merged as the downstream processes will need updating (as the current response names will no longer match).

on hold, waiting for backend system to be updated first so that downstream processes are properly handled

Delta meeting:
check if response files of, say, Basalt and Basalt/8 , are the same or not.
If the same, use Basalt instead of Basalt/8
