*OPT? command was added in the 1.5.2R1 SDS2000X+ firmware. This can be used to check licensed features.

Maybe this could be used to address this TODO for at least newer versions: https://github.com/glscopeclient/scopehal/blob/148899e23459d7417414a6cc3727053ade69ae77/scopehal/SiglentSCPIOscilloscope.cpp#L338-L340

This will also be useful for only enabling protocol triggers and MSO channels if the scope has the relevant feature installed.
