Add Chinese (Simplified) translation

[yanang007]

Thanks for your immersive mod! And this is a Chinese Simplified translation for this mod. I noticed that (probably) "%d colors", "%d%% dither", "%d%% X offset", "%d%% Y offset", "%d%% zoom" is not present in the lang file. It would be good if they are translatable! In case you need it, these are translations for those entries:

• "%d colors": "%d 色"
• "%d%% dither": "颜色抖动：%d%%"
• "%d%% X offset": "X偏移：%d%%"
• "%d%% Y offset": "Y偏移：%d%%"
• "%d%% zoom": "缩放：%d%%"

Please let me know if any improvement is needed!
