OpenSSL 3.0 Support

[bak1an]

@sukeerthiadiga Are you seeing any specific issues with openssl 3.0?

[bak1an]

Ok, I found exact issue.

With following patch I have tests passing with ruby 3.2 and openssl gem 3.2 (required to get OpenSSL::Provider, else openssl env config required for legacy ciphers) built against openssl 3.3:

3.2.4 :001 > require 'openssl'
 => true
3.2.4 :002 > OpenSSL::VERSION
 => "3.2.0"
3.2.4 :003 > OpenSSL::OPENSSL_LIBRARY_VERSION
 => "OpenSSL 3.3.0 9 Apr 2024"
3.2.4 :004 > RUBY_VERSION
 => "3.2.4"

I do have a branch for this there https://github.com/macks/ruby-ntlm/compare/master...bak1an:ruby-ntlm:openssl3

@macks Would you be interested in a PR to properly release this?

Having openssl 3.2 gem as a dependency will require limiting minimal ruby version to 2.7 (and will ideally mean some code cleanup here) but it seems fine to me. Older ruby version will not be affected by openssl 3 anyway so they can just use older gem version.
