Support "real" fluent accessors (getters/setters)

[spirann]

The actual support of so called "fluent" setters is more a support of "chained" setters.

Mapper<FluentSetterDto, FluentSetterDto> m = Mapping.from(FluentSetterDto.class)
        .to(FluentSetterDto.class)
        .allowFluentSetters() // **should be called "allowChainedSetters()"**
        .mapper();
FluentSetterDto expected = new FluentSetterDto().setInteger(5)
        .setI(22)
        .setS("str")
        .setB1(true)
        .setB2(true);
FluentSetterDto actual = m.map(expected);

Fluent accessors are using directly the name of the attributes (see Java records and Lombok Accessors)

FluentSetterDto expected = new FluentSetterDto().integer(5)
        .i(22)
        .s("str")
        .b1(true)
        .b2(true);

But they are not currently supported.
