Update node-watch so recursive watch is enabled on linux

[laurentpayot]

platform: Linux (Ubuntu 20.04 LTS)
node version: 14.12.0
elm-analyse version: 0.16.5

If I run % elm-analyse -s I get:

Elm Analyser server starting with config:
{
  port: 3000,
  elmFormatPath: 'elm-format',
  format: 'human',
  open: false
}
fs.js:1471
    throw new ERR_FEATURE_UNAVAILABLE_ON_PLATFORM('watch recursively');
    ^

TypeError [ERR_FEATURE_UNAVAILABLE_ON_PLATFORM]: The feature watch recursively is unavailable on the current platform, which is being used to run Node.js

}

I fixed this by updating node-watch to the latest version:

cd node_modules/elm-analyse && npm i node-watch@0.6.4
