Change to code that doesn't use boost

[neoarc]

I don't know if this is an unreasonable demand.

While reviewing the use of this IPC library, I was asked if boost was absolutely necessary.

At this point, most of them can be replaced by standards such as c++17.

The internal code is well written, but the usability is not the best.

How do you think?

all of the shared memory stuff is boost::interprocess, I don't think that's in c++17
