Add support for lyrics

[danielepintore]

In this pull request I've added support for lyrics.

When we make a scan now we check for lyrics inside the file using taglib, once the scan process in finished we have all lyrics saved on the db so we can retrieve them faster. When we are looking for a lyrics it first checks if there is a embedded lyric, if there is we return that, otherwise it looks for a file SONG_NAME.lrc and reads the lyrics from it. If there isn't a .lrc file an empty response is provided.

I've added support for both getLyrics and getLyricsBySongId methods. I have even created a migration, but i'm not so sure if that works fine maybe give that a double check.

Let me know if there is something to change.
P.S. I have used some code from #488

thanks for work here, but is this a dupe of #488 ?

[danielepintore]

Not exactly a dupe since I've added also the possibility of fetching the lyrics from the embedded tag. Since i couldn't work on that pull request I've decided to make a new one. I should have implemented all things that weren't implemented on the other pull request

How can i test it? I can't understand how to build it

Hi, I suggest to build a custom docker image and use that in your docker-compose.yaml.

1. Clone the repo: git clone [email protected]:danielepintore/gonic.git
2. cd gonic
3. Build the image: docker build . -t gonic_lyrics:latest
4. Replace in the docker-compose the image name with gonic_lyrics:latest
5. Run the container the same way you do for the standard version docker compose up -d

These are the steps needed to build and use the image, but i have noticed that it returns an error. The problem is the one fixed by #526. Changing the Dockerfile with the changes proposed by #526 fixes the issue and let you build the image.

That's works. Thank you!
