New features

• Expose ensureXXXXX helper functions from mod.ts
• Improve documentation of public interfaces

💥 Incompatible changes

The following are incompatible changes so that user who use that feature must fix them code.

• Remove denops#lib#promise and it's related features
  • Use Async.Promise of vital.vim instead
  • Use denops#request_async() instead of denops#promise()
• Remove denops#lib#job and move implementations into denops#utils

  • Chaged from dispatch(name, fn, args) to dispatch(name, fn, ...args)

🚪 Internal incompatible changes

The following are assumed as internal changes so plugin developers who use denops-std module should not be affected by those changes.

• Remove dispatch/dispatchAsync/register from Vim/Neovim communication layer and replaced those commands with invoke message
