[Bug] pillars do not get destroyed in Surreptitious Seven-Star Seal Sundering

[scooterboo]

Surreptitious Seven-Star Seal Sundering is a required world quest for the chapter 2 plot to continue. here: The pillar dips when you hit it, but nothing else happens.

This commit fixes a bunch of issues: https://github.com/Anime-Game-Servers/Grasscutter-Quests/pull/161 But what it doesn't fix is that these pillars are point arrays and https://github.com/Anime-Game-Servers/Grasscutter-Quests/pull/156 doesn't have code for handling isReachEvent. isReachEvent means that EventType.EVENT_PLATFORM_REACH_POINT gets called when the platform reaches that point. Current point array code does not have that delay calculated.

Which branch did you use? refactoring_multiproto_0.2 Grasscutter version: 1.4.4-dev-48ebfc6f Git Hash: 48ebfc6ff36ac2078388da0f5d9a74cbfbe72461 (it's local)
