Build multiple file types in one go

Currently if we want to output an STL, a STEP and a GLB we have to run all cq-cli 3 times. However as `main.py` runs cadquery to get the build result and then passes it into the codec, it would be possible just to repeat the codec step which should add some speed.

I can imagine semicolon separating should work:

cq-cli --infile /input/path/script.py --outfile /output/path/newfile.step;/output/path/newfile.stl;/output/path/newfile.glb

If the user specifically wanted to set codecs it could be a list that needs to be the same length

cq-cli --codec step;stl;glb --infile /input/path/script.py --outfile /output/path/newfile.step;/output/path/newfile.stl;/output/path/newfile.glb

先阅读 main.py，跟踪 CadQuery 构建结果生成后 cq-cli 如何解析 --outfile 和 --codec。使用 issue 中的 STEP、STL 和 GLB 示例验证行为；当一次调用能够支持多个输出而无需重复 CadQuery 构建时，即表示完成。
