@neodx/svg Reborn CLI

[secundant]

The @neodx/svg CLI is currently not shown in the documentation and readme due to deprecations caused by a lack of control and poor configuration design.
However, some users need to build sprites externally without using bundlers.
Therefore, I need to restructure the configuration practices for @neodx/* and provide a flexible CLI that can be easily configured.

Possible design:

// .neodxrc.js

export default {
  svg: {
    inputRoot: './assets/icons',
    output: './public/sprites',
    // ...
  }
}

yarn sprite
# or
yarn svg build
