Support configuratable directories

[mantaroh]

What is this?

This change make a Spear to be configuratable directories:
The spear allow the following directory:

setting key of spear.config.mjs	value type	description
srcDir	string array	source directory which need to build
componentsDir	string array	components directory which need to parse and bundle
distDir	string	destination directory

You need to write these directories into spear.config.mjs.

e.g.,:

export default {
  "spearlyAuthKey": "xxxxxxxxx",
  "projectName": "local-test",
  "generateSitemap": false,
  "srcDir": ["src", "src/components", "src/pages" ],
  "componentsDir": ["src/components"],
  "distDir": "dist",
};

Note

1. If srcDir include the child directory, spear might remove child directory. (In above sample settings, src/page will be removed.)
2. If srcDir has the directory which end with components, spear will not remove it even if it's child directory.
   • This reason is that user might generate the component result.
