c环境初始化问题

[ZeyanZhuang]

GoBigger C 环境无法初始化食物球、克隆球的位置和大小，是 BUG 还是和 Python 环境初始化的方式不一样呢？

@ZeyanZhuang 麻烦提供一下config和启动环境的代码？我们这边测试了是正常的

我也遇到了类似的问题，食物的最大数量是4，在cpp的环境中，reset后看到的食物数量的2000，这是我测试用的代码以及log。

@Jingho 这个问题已经在这个commit 修复了，是由于config没有同步到c++端导致的。但是由于一些奇怪的原因，需要地图内的总球数（包括各种球）大于（4+总玩家数*4） @ZeyanZhuang C++暂时不支持直接从custom_init这个参数来初始化，但可以通过jump_to_frame_file这个参数来初始化
