v3.6.6

1. fixed ObjectUtils key conflicts
2. add support for SmartSqlMapper multiple instance injection
3. add support for IServiceProvider.GetSmartSqlMapper(string configPath)

      var smartSqlMapper = serviceProvider.GetSmartSqlMapper("SmartSql");
      var smartSqlMapper_1 = serviceProvider.GetSmartSqlMapper("SmartSql-1");

4. optimize Options DI for SmartSqlOptions.UseOptions

            var builder = new ConfigurationBuilder()
                .SetBasePath(Directory.GetCurrentDirectory())
                 .AddJsonFile("SmartSqlConfig.json", false, true);

            var configuration = builder.Build();
            var services = new ServiceCollection();

            services.AddOptions();
            var smartSqlConfigJson = configuration.GetSection("SmartSqlConfig");
            services.Configure<SmartSqlConfigOptions>("SmartSql", smartSqlConfigJson);

            services.AddSmartSql(sp =>
            {
                return new SmartSqlOptions
                {
                     ConfigPath= "SmartSql"
                }.UseOptions(sp);
            });
