feat(drivers): add autoindex driver

[KirCute]

Description / 描述

基于antchfx/htmlquery爬取 autoindex 页面。由于各 web 服务器的 autoindex 页面各不相同，需要自己写 XPath。

Motivation and Context / 背景

https://github.com/orgs/OpenListTeam/discussions/170#discussioncomment-14943992

How Has This Been Tested? / 测试

测试环境1为 Apache/2.4.18，所用 XPath 如下：

• 条目：//table/tbody/tr[position() > 2]
• 文件名：./td[2]/a
• 修改时间：./td[3]
• 文件大小：./td[4]

测试环境2为 nginx/1.29.0，所用参数如下：

• 条目：//pre/a
• 文件名：.
• 修改时间：substring(normalize-space(./following-sibling::text()[1]),1,17)
• 文件大小：substring(normalize-space(./following-sibling::text()[1]),19)
• 修改时间格式：02-Jan-2006 15:04

测试环境3（本地）为 Caddy/v2.10.2，所用参数如下：

• 条目：//table/tbody/tr
• 文件名：./td[2]/a/span
• 修改时间：./td[4]/time
• 文件大小：./td[3]/div/div[2]
• 忽略文件名：Up
• 修改时间格式：01/02/2006 03:04:05 PM -07:00

测试环境4（本地）为 SimpleHTTP/0.6 Python/3.11.5，所用 XPath 如下：

• 条目：//ul/li
• 文件名：./a
• 修改时间：没有，所以为空
• 文件大小：没有，所以为空

测试环境5响应头里只写了 Apache 没写版本，所用参数如下：

• 条目：//pre/pre/a
• 文件名：.
• 修改时间：substring(normalize-space(./following-sibling::text()[1]),1,16)
• 文件大小：substring(normalize-space(./following-sibling::text()[1]),18)
• 忽略文件名：添加Name、Last modified、Size、Description

Pull request overview

This PR adds a new "Autoindex" driver that can crawl and parse autoindex pages (directory listings) from web servers like Apache using XPath expressions. The driver uses the antchfx/htmlquery library to parse HTML content and extract file information.

Changes:

• Added autoindex driver with configurable XPath expressions for parsing different autoindex formats
• Implemented List and Link operations for browsing and accessing files from autoindex pages
• Added size parsing utility that handles various unit formats (K, M, G, etc.)
