Besides initializing the CAS and the CSIS, there are also commands to lock and release the CSIS
instance, as well as printing and modifying access to the SIRK of the CSIS.
Setting a new SIRK
------------------
This command can modify the currently used SIRK. To get the new RSI to advertise on air,
:code:`bt adv-data`` or :code:`bt advertise` must be called again to set the new advertising data.
If :code:`CONFIG_BT_CSIP_SET_MEMBER_NOTIFIABLE` is enabled, this will also notify connected
clients.

Getting the current SIRK
