#1040
OpenWebGAL/pixi-live2d-display-webgal#16
由于Cubism Web SDK实现上的问题，当载入的Live2D立绘的内存总占用达到一定限度、触发了Emscripten堆扩容时，已载入的立绘将无法正常更新。具体的问题原理解释，见pixi-live2d-display-webgal#16的描述。
该改动通过PLDW提供的内存预留API，允许提前为Live2D预留更大的Emscripten堆内存空间。这将在一定程度上增大项目的内存占用。默认的堆空间提升至32MB，一般情况下足够满足正常演出所需。
同时，提供config.txt中的新配置项
Cubism_Memory_Reserved_Size_MB，类型为number，单位为MiB，允许用户为项目自定义配置cubism core堆内存预留容量，支撑更多live2d模型的显示需要。
