Register only the correct amount of tiles by rotation

In this branch of my fork https://github.com/MrAmericanMike/Wave-Function-Collapse/tree/better-tile-initialization

I created an "addTile" function. Basically what it does is push a new tile to the tiles array and if rotation is greater than 1 it will grab the last tile from the tiles array and push it as a new tile rotated 90º. (Notice we always rotate 90º as we are using the last tile from the array.

首先将仓库与链接的 fork 中的 better-tile-initialization 分支进行比较，重点关注 issue 中描述的 addTile 函数和 tiles 数组。跟踪旋转值如何注册 tiles，然后确认生成的数组只包含预期数量的旋转 tiles。
