Bug: Translator Causes Negative Prompt Became Positive Prompt

[MaikoTan]

Describe the bug

According to "les amies de groupe", only the Baidu translator does such a fun fact, the Youdao translator perhaps well instead.

So when we want to add the negative prompt, we can use -u, --undesired, and negative prompt: to achieve this.
But when you enable the translate feature, the translator would translate -u into - u, or even ate the -u part, so then the negative prompt part would become ridiculously the prompt itself!

Steps to reproduce

1. Starts Koishi with NovelAI-Bot plugin
2. nai une fille petite -u lowres, jpeg artifact, mauvais hand
3. the actual prompt became little girl, big breasts, bad hair, bad eyes, bad hands (the -u was eaten)

Expected behavior

Being able to use -u and --undesired properly.

A better workaround is to split positive and negative prompt before feeding them to the baka translator.
I am trying to fix this but I don't know how to achieve it. Also there would be 2 http requests if we split them out first.

Don't know if Baidu or Youdao has a rate limit on translate API, but it looks like sending two requests concurrently (with Promise.all()) is still useful here.
So it looks like a prompt parser is still needed here. Does anyone have thoughts?
