Changed parser option checks to allow artist search

[Spyridion]

I noticed the if checks stop the artist tag from being used. I added the nots to allow the artist search to continue to the legacy search function.

Hi, I just noticed that the dev branch doesn't have the artist specific changes from master branch.

Will you be cherry picking from dev into master?

I also had to do a sudo pip install lxml to get the build to work as well. I get this error otherwise: bs4.FeatureNotFound: Couldn't find a tree builder with the features you requested: lxml. Do you need to install a parser library?

Merged to master branch.

Seems better to use soup = BeautifulSoup(s, "html.parser") to parse html content, this way isn't need lxml dependency

Yeah, that makes sense. There were a couple changes I didn't notice between dev and main when I made this pr.
