v5.2

• More options (comms::option::def::VariantHasCustomResetOnDestruct and comms::option::def::HasVersionDependentMembers) for the comms::field::Variant field to allow faster compilation.
• Added new comms::field::Variant::deinitField() member function to support explicit de-initialization (destruction) of the member field.
• Deprecated and removed support for multiple calls for comms::field::Variant::initField() without call to deinitField() or reset() member functions in-between.
• New options (comms::option::app::MsgFactory and comms::option::app::MsgFactoryTempl) to allow overriding message factory class (comms::MsgFactory) used by the comms::protocol::MsgIdLayer to create the message object.
• Added new COMMS_PROTOCOL_LAYERS_NAMES() in addition to the COMMS_PROTOCOL_LAYERS_ACCESS() which also defines alias types.
• Deprecated and removed comms::field::NoValue field.
• Added more constexpr member functions to the comms::MessageBase and all the fields to inquire about the used extension options.
• Some small doxygen documentation improvements.
