Support for Everything 1.5 SDK

[Everything 1.5 SDK](https://www.voidtools.com/forum/viewtopic.php?t=15853) was released half year ago. It replaced `WM_COPYDATA` with named pipes and the performance is much better. There are also many new APIs. Is there any plan to support it?

FYI, I've also asked at https://github.com/owtotwo/everything-sdk-rs/issues/2
