✨ full and partial changelog generation

[bpetetot]

New process to generate full and partial changelog.

By default, when executing the CLI with ./gitmoji-changelog:

• If CHANGELOG file doesn't exists, a full changelog is generated
• If CHANGELOG exists, a partial changelog is generated, it can be:
  • the next version (must be given by the user or read from package.json)
  • the next release (current work)

We can also have separated CLI commands:

• ./gitmoji-changelog init: full changelog generation
• ./gitmoji-changelog update [version|next]: partial changelog generation (by default: package.json)

Fixes #25

This test works but it is not full, I didn't succeed to mock streams of fs, it runs in conflict with jest that use fs internaly. We should find a better way to mock fs

I don't understand why you don't end to end pipe

const { Transform } = require('stream')
// [...] 
fs.createReadStream(currentFile)
  .pipe(es.split())
  .pipe(new Transform({
    transform(chunk, enc, callback) {
        if (line.startsWith(`<a name="${lastVersion}"></a>`)) {
          lastVersionFound = true
        }

        if (lastVersionFound) {
          callback(null, `${line}\n`)
        } else {
          callback()
        }
    },
  })
  .pipe(writer)

It doesn't work ?
