DirectoryTree - Missing custom field support in typescript interface

[lukasrandom]

Hey,
just tried to add custom field to DirectoryTree object in typescript inside a DirectoryTreeCallback. The following error occured:

Error:

error TS7053: Element implicitly has an 'any' type because expression of type '"id"' can't be used to index type 'DirectoryTree'.
  Property 'id' does not exist on type 'DirectoryTree'.

34     item['id'] = createHash('sha1').update(path).digest('base64');

Example adding custom id field:

import directoryTree, {
    DirectoryTree,
    DirectoryTreeCallback,
} from 'directory-tree';
import { createHash } from 'crypto';

const path = 'C:/Users/me/Desktop/a';
const callback: DirectoryTreeCallback = (item: DirectoryTree, path: string) => {
    item['id'] = createHash('sha1').update(path).digest('base64');
};
const dirTree: DirectoryTree = directoryTree(path, {}, callback, callback);
console.log(JSON.stringify(dirTree, null, 2));

Fix:

Added [key: string]: any in to the DirectoryTree interface at node_modules\directory-tree\index.d.ts.

Already opened an issue here:
#103

Best
Lukas

@lukasrandom hey, thanks for this! Do you think maybe it'd make more sense to group all of these into some sort of extra object? So at least they are still packed together? Happy to accept the PR otherwise.
Thanks!

@mihneadb
Thanks to the feedback :)
New commit adds the "custom" field on the "DirectoryTree" interface to encapsulate additional extra information.

@lukasrandom thanks! Looks good, with the mention that it appears the indenting was changed from spaces to tabs :S. Please leave it as it was. Oh and it might be worth adding 1-2 words about this new option in the Readme, if you find a place for them.
Thanks!

Fixed the formatting issue to stay to the original. Didn't noticed that prettier was changing the formatting.
Added a small readme entry.
