已知1：室内局部三维坐标点（x、y、z）； 通过三个点（a、b、c）室内三维坐标与大地三维坐标对应的关系；将室内局部三维坐标转换成对应的大地三维坐标？ 要求1：请使用java代码通过GeoTools实现，并分别指出用到了哪些库、哪些jar包、哪个版本； 要求2：给出完整使用示例；

要求1：

该问题可以通过GeoTools中的CoordinateReferenceSystem（CRS）和MathTransform类实现。需要用到以下库和jar包：

- GeoTools核心库：gt-main、gt-referencing、gt-metadata
- GeoTools中的CRS和MathTransform类：gt-referencing和gt-epsg-wkt

GeoTools版本：22.0

要求2：

以下是完整的使用示例，包括了转换前后的坐标点和转换矩阵的输出：
