`.do` arguments not passed correctly

The current implementation of the callback chain in 5a-chain passes data from the previous callback but doesn't pass arguments explicitly mentioned in .do().

In usage example readConfig callback is expected to receive myConfig as an argument.

const startChain = chain()
  .do(readConfig, 'myConfig')
  .do(selectFromDb, 'select * from cities')
  .do(getHttpPage, 'http://kpi.ua')
  .do(readFile, 'README.md');

However it receives undefined instead.

So if callbacks would really depend on the previous one the chain would fail once it was called.

Also, should only the first callback in the chain receive an explicit argument, and the following ones receive their arguments from the previous one? Or should they receive both explicit and implicit arguments?

まず、5a-chain の callback チェーン実装と、readConfig、selectFromDb、getHttpPage、readFile を示している使用例を調べます。各 .do() 呼び出しを通じて引数がどのように渡されるかを追跡し、その後、ドキュメント化された callback が undefined ではなく、期待される明示的な引数と前の callback の引数を受け取ることを確認します。
