使用 C# 实现的 Ryu ，一个高性能浮点数转换为字符串的算法。
Ryu, implemented by C#, a high-performance algorithm for converting floats to strings.
- To avoid managed memory fragmentation, the implementation was changed from pointers to references. (The difference between pointer and reference is that the former is an unmanaged pointer and the latter is a managed pointer.)
- Inherit the open source license of the parent project to make it easier for everyone to use.
- fix bugs.
- Publish nuget package.
