Increase in the number of laboratories and complexity of research

new laboratories and a new setting at the start of the game that allows you to include a more complex system of research in case of inclusion instead of one laboratory will be three (for example, chemistry and metals, construction and transportation, electricity and mining) they can be more, which for example will allow you to research up to 3 technologies in different directions, but for example, research will require more different resources (for example, everything related to electricity will require in addition to research packages electric cable and pay with processors on the late game) and we can let you build ordinary labs, but their efficiency will decrease as technology advances.
