Move to Electron v10, node.js v12

Also, upgrade serialport from 7.x to 9.x

Works/uploads fine on my machine 👍 (I use Arch, BTW)

The only thing I spotted is a couple of warnings at the very beginning of execution:

$ XOD_ARDUINO_CLI=/home/nailxx/xod/arduino-cli yarn start:electron      
yarn run v1.22.10
$ lerna run start --scope xod-client-electron --stream
xod-client-electron: $ electron .

Are they ours or from a dependency?

We don't call Buffer anywhere in our codebase. Must be a dependency.
