Is your feature request related to a problem?

class MyClass:
{
 void setup()
 {

    i2cinput.onRequest([this]() {
      // dothings
    });
 }
};

void (*user_onRequest)(void);
void (*user_onReceive)(int);

void onReceive(void ()(int)) override;
void onRequest(void ()(void)) override;

Describe the solution you'd like

this instead 🤔
std::function<void()> user_onRequest;
std::function<void(int)> user_onReceive;
void onReceive(std::function<void(int)> function);
void onRequest(std::function<void()> function);

Describe alternatives you've considered

manually changing the lib locally
