Add logHandler callback as option to handle logs

[zcmgyu]

Description:

When I use appium-doctor in the NodeJS project (not as CLI), I couldn't handle logs without add callback function.

Usage:

function onLogMessage (level, prefix, msg) {
    console.log(level);
    console.log(prefix);
    console.log(msg);
}

configureBinaryLog({ onLogMessage });

Detail Usage in Project:

import { system } from 'appium-support';
import { newDoctor } from 'appium-doctor/build';
import { configureBinaryLog } from 'appium-doctor/build/lib/utils';
import { configure as configurePrompt } from 'appium-doctor/build/lib/prompt';

(()=> {
    function onLogMessage (level, prefix, msg) {
        console.log('DEBUG level', level);
        console.log('DEBUG prefix', prefix);
        console.log('DEBUG prefix', prefix);
    }

    const opts = {
        general: true,
        ios: system.isMac(),
        android: true,
        onLogMessage,
    };

    configurePrompt(opts);
    configureBinaryLog(opts);
    const doctor = newDoctor(opts);

    doctor.run().then(() => {
        console.log('DEBUG doctor.toFix', doctor.toFix);
        console.log('DEBUG doctor.toFixOptionals', doctor.toFixOptionals);
    });
})();
