2023-04-29 18:54:06 Sola v0.0.3 加入了从WRF读取数据, 以及输出cartopy.crs的功能
2023-09-07 10:42:59 Sola v0.0.4 设定了默认的地球形状, 以修正默认投影与模式的偏差, 加入globe参数
感谢韩雨阳的帮助, 指出了两个差异的问题所在
2024-07-22 20:36:52 Sola v0.0.5 增加了判断坐标（坐标数组）是否在模式网格内的功能
2024-12-18 10:11:55 Sola v0.0.6 增加了与墨卡托投影相关的计算内容
2025-04-06 16:39:26 Sola v0.0.7 增加提供网格中心坐标计算网格的功能（优先级低于左下角坐标）
2025-04-06 16:45:22 Sola v0.0.8 增加坐标旋转功能
2023-12-28 15:42:11 Sola v0.0.5 增加了加密网格的功能
2023-12-28 15:54:53 Sola v0.0.6 增加了获取绘图范围的功能, 并使其接受浮点数输入

2025-04-06 16:45:22 Sola v0.0.10 增加坐标旋转功能
修改的关键在于：
1. 在将经纬度转化为网格的时候, 围绕中心对网格进行偏移旋转, 需要增加一步后处理
2. 在将网格转化为经纬度的时候, 需要先将输入的网格ID旋转回去, 再计算其经纬度

2023-03-18 16:09:39 Sola 编写源代码
2023-03-18 16:21:46 Sola 测试功能正常, 从网格到经纬度及反向都正常
2023-10-18 16:19:10 Sola 增加了将结果展开成2D的功能
2023-12-28 15:38:53 Sola 调整了数组顺序, 方便最终展开
