1.0.29 release

虽然 Ventoy 显示了 Unofficial 的标注信息，但是用户并不会关心，仍然会认为是 Ventoy 的问题。

Ventoy 从一开始就是一个整体的设计，并没有考虑过集成在其他bootloader或分区环境中。
Ventoy 的验证和后续新功能开发也都不会考虑这种非标准的使用方式。

因此，我决定禁止 Ventoy 在非标准环境下的使用，并且不再接受放开检查的请求。

当然，这个只是Ventoy的默认行为。Ventoy仍然是100%开源的，如果你希望把Ventoy应用在自己的环境中，你可以fork一个分支，然后修改源代码实现。

 1. Compile Enviroment
 ==========================================
     My build envrioment is CentOS 7.8 x86_64. So here I first explain how to create the build environment from scratch.
-    Because Ventoy is based on many open source projects, so the envrioment is important. I suggest you test it on a virtual machine first.
