Consider support latest version of Node

[Dentrax]

This is a great tool! I like to use this very much. It's my primary to record my terminal. But...

Unfortunately, it does not support the latest version of Node (v16). Each time I do brew upgrade, my node bumps to its latest version. And I have to do the following steps every time in order to make terminalizer work:

1. brew unlink node
2. brew install node@12
3. brew link --overwrite node@12
4. npm install -g terminalizer

I do not like to dealing with npm stuff since it's too "noisy" and does not work as expected in general. I would be so glad if someone gets to it to make it work with the latest node versions. Thanks! :)
