Update to a new CwlDemangle version (1.2.0) that supports emitting a 'summary' format of the demangled symbol data that includes only what launchpad actually consumes. Testing locally suggested for large binaries a large amount of CPU was wasted serializing JSON that we don't actually need, which slowed things down. This will be enabled via a new option and rolled out incrementally just to be safe.
