Security vulnerability

[goncedillo]

Hi there,

first of all I want to thank you for your impressive work. It is really great to have a tool like this for the community. So tanks in advance 😉

I have a CLI tool called mockium that uses your package for offereing multiple and connected panels in the terminal.

Recently I noticed that my package process was warned because a security issue related to Lodash in one of your dependencies. So I decided to give you a hand with it and update the version in order to fix the vulnerability.
I opened a PR for that. I hope this small contribution helps you with your fantastic package.

Again. Thanks for your work

The lodash vulnerability is now fixed through an upgrade of pegjs-otf, but the xterm.js related one cannot be fixed.
