Add missing functionality for glob compatibility

[simlu]

The ultimate goal is to get this library into a state where we can use it to power very efficient glob matching. The functionality is almost there. Missing:

• Arbitrary depth matching of specific patterns, e.g. *(pattern), @(pattern) etc. Have to better understand how pattern are used with file extensions, e.g. what does 'source/*(some|file).py' mean?
• Full regex support. Maybe we can just support that inside ()?

See here for more information: https://facelessuser.github.io/wcmatch/glob/#syntax

Once equivalent functionality is fully supported it should be possible to write a glob library powered by object-scan.

Regex support is WIP here: https://github.com/blackflux/object-scan/pull/1247/files

This might not be that hard actually:

const isEqual = require('lodash.isequal');
const fs = require('smart-fs');
const path = require('path');
const objectScan = require('object-scan');

const list = (needles, folder) => objectScan(needles, {
  breakFn: ({ key, value, isMatch, context }) => {
    const p = path.join(folder, ...key);
    const stats = fs.lstatSync(p);
    const isDir = stats.isDirectory();
    const isFile = stats.isFile();
    if (isDir) {
      fs.readdirSync(p).forEach((f) => {
        value[f] = {};
      });
    } else if (isFile && isMatch) {
      context.push(path.join(...key));
    }
  }
})({}, []);

const p = path.join(__dirname, 'node_modules');
const r1 = list(['**'], p);
const r2 = fs.walkDir(p);
console.log(isEqual(r1.sort(), r2.sort()));

Should have everything available now to write a glob library 👍

Closing this. Eventually someone might build a glob library on this. Maybe me, maybe not =)
