active-cache-babel-register improves performance of babel transpilation using cache actively.

## Cache Strategy

- babel finds config files and load these files every startup time, active-cache-babel-register set the config files to cache registry.
- babel-register does not support multi-process cache like cluster/child_process, active-cache-babel-register has 2 cache stores, 1st cache store is original one, 2nd cache store can be used in multi-process
- active-cache-babel-register purges cache if babel-version/.babelrc/package.json/.babelignore and target files are changed

## Performance

## Usage
