Feature/get device by id without permission

[hugomontero]

• Remove prompting permissions for web-usb getDevices.
• Add a new method: requestDevice to grant usb permissions for an specific particle device.
• openDeviceById, now will use serialNumber for an specific webusb device.

How to test:

Using a web project do:

import {  requestDevice, getDevices, openDeviceById } from 'particle-usb';
try {
		const devices = await getDevices();
		console.log('my devices', devices);
		const device = await requestDevice();
		console.log('my device', device);
		console.log('opening the first device', devices[0]);
		const openedDevice = await openDeviceById(devices[0].id);
		console.log(openedDevice);
	} catch (error) {
		console.log(error)
	}

outcome

• getDevices will return a list of granted and connected particle devices
• requestDevice will prompt you to pick a device to grant usb permissions to the browser
• opendeviceById pick a device ( in this case from the list of devices) and it will open it and allow you to run commands thru the device.
