Strange Typo "ixivDownloader" before constant PIXIVUTIL_VERSION

Prerequisites

• Did you read FAQ section in readme.md?
• Did you test with the latest releases or commit ?
• Did you search for existing issues in Issues?

Description

Each time the program is launched and for each image downloaded, the line is prefixed with ixivDownloader 20210421 in the console.

Steps to Reproduce

1. Launch the script
2. The first printf of header() will have the prefix ixivDownloader 20210421
3. Each Member ID page processed will also have this invalid prefix ixivDownloader 20210421 [1 of 1] MemberId: 988539 Page: 1Member Url: https://www.pixiv.net/ajax/user/988539/profile/all (There is also improper spacing here between “Page” and “Member Url”)
4. Each Image ID processed which is not already downloaded will have this invalid prefix ixivDownloader 20210421 [1 of 1] MemberId: 474309 Page: 1 Post 2+0 of 460 ImageId: 89236210Title: あー？何上から目線で見てんだタココラッ！ (More improper spacing between “ImageId” and “Title”)

Expected behavior: The name of the program and version would not be displayed in all these circumstances, much less with a typo.

Actual behavior: An incorrect name of the program as well as the version of the program is printed extremely frequently.

Versions

PixivDownloader2 version 20210421 (if it wasn’t obvious already)
