Please support the new BV tags

[yicong2007]

According to 【升级公告】AV号全面升级至BV号,the AV tags have been upgraded into BV tags.

The regular expression in lib/extractor.js

var REGEX_URL_VIDEO = /^https?:\/\/(?:www\.|bangumi\.|)bilibili\.(?:tv|com)\/(?:video\/av(\d+)(?:\/|\/index_(\d+)\.html)?)(?:\?p=(\d+).*)?$/i;

is outdated and the video id cannot be extracted so easily as before.

This is only a temporary solution and I'm using bilibili-get on windows node.js (v12.16.1). If your environment is similar to me, this solution may help you. I guess it'll work on the other environments too.
Please change following lines in extractor.js.

• top of the file

// var REGEX_URL_VIDEO = /^https?:\/\/(?:www\.|bangumi\.|)bilibili\.(?:tv|com)\/(?:video\/av(\d+)(?:\/|\/index_(\d+)\.html)?)(?:\?p=(\d+).*)?$/i;
var REGEX_URL_VIDEO    = /^https?:\/\/(?:www\.|bangumi\.|)bilibili\.(?:tv|com)\/(?:video\/BV([A-Za-z\d]+)(?:\/|\/index_(\d+)\.html)?)(?:\?p=(\d+).*)?$/i;

• var result = Object.assign({

// video_id: parseInt(REGEX_URL_VIDEO.exec(url)[1]),
video_id: REGEX_URL_VIDEO.exec(url)[1],

• var findVideoInfo = function* ({ video_id, part_id, cookie }) {

// var data = yield fetchWebPage(`https://www.bilibili.com/video/${video_id}/` + (part_id ? `index_${part_id}.html` : ''), { cookie });
var data = yield fetchWebPage(`https://www.bilibili.com/video/BV${video_id}/` + (part_id ? `?p=${part_id}` : ''), { cookie });
