Exception messages need to be in english

[LosWochos76]

The message of any exception needs to be in english language. Otherwise, this package can only be used by people capable of reading mandarin.

Over 460000 downloads on nuget, but no english messages? Perhaps, this repo is only for the chinese market! Just an idea, in case this repo should be used all over the world: use a simple bool parameter in all ctor's: ctor(Param1 param1, bool enableEnglish = false), and define the exception messages _enableEnglish ? "English text" : "Chinese text".
