Compile failure with boost >= 1.87

[nh2]

On Version 18.73:

Trying to compile with boost >= 1.87 does not work because boost 1.87 removed/renamed `io_service:

Src/Socket.h:56:29: error: 'io_service' in namespace 'boost::asio' does not name a type; did you mean 'use_service'?
   56 |         static boost::asio::io_service io_service;
      |                             ^~~~~~~~~~

How to fix (probably)

Example how to handle this update from PCL, switching to boost::asio::io_context (seems to be a small code change in general):

• PointCloudLibrary/pcl@0932486
• [compile error] boost 1.87: error: ‘io_service’ in namespace ‘boost::asio’ does not name a type; PointCloudLibrary/pcl#6202
