Add support for Boost 1.87.0 (Boost.Asio removals)

[cho-m]

• Your operating system name and version?

Tested on Homebrew CI so macOS 13-15 and Linux Ubuntu 22.04

• Please attach your /etc/fastnetmon.conf configuration file
• What capture engine are you using: Netflow, sFlow, miror?
• If you are using Netflow or sFlow, please specify version, vendor name, model name and firmware of agent device.
• Please attach /var/log/fastnetmon.log

N/A as related to compilation rather than running.

---

Advance notice that FastNetMon does not compile with upcoming Boost 1.87.0 (based on beta1) as Boost.Asio has removed the deprecated io_service boostorg/asio@ec0908c

This causes errors like:

fastnetmon-1.2.7/src/fast_library.cpp:1090:22: error: no type named 'io_service' in namespace 'boost::asio'
 1090 |         boost::asio::io_service io_service;
      |         ~~~~~~~~~~~~~^

Also need to remove boost::asio::ip::tcp::resolver::query and change code as described in https://www.boost.org/doc/libs/1_86_0/doc/html/boost_asio/net_ts.html

fastnetmon/src/fast_library.cpp

Lines 1097 to 1102 in a813f7d

	boost::asio::io_service io_service;
	boost::asio::ip::tcp::resolver resolver(io_service);
	boost::asio::ip::tcp::resolver::query query(domain_name, "");
	for (boost::asio::ip::tcp::resolver::iterator i = resolver.resolve(query);

Easiest option is to require a minimum of Boost 1.66.0 (boostorg/asio@b60e92b) and update APIs, which may be possible as code already uses io_context:

fastnetmon/src/fast_library.cpp

Line 1520 in a813f7d

boost::asio::io_context ioc;

Hello!

Thank you very much for reporting this issue! I'll look on it shortly
