Need fetching more metadata types

[realth000]

1. I'm trying to read metadata from mp3 files, however, some images in 'Disc' position were not found when using MetadataGod.getMetadata() method.
   That mp3 file with id3v2 format metadata has an album cover image named as 'Disc'.

(foobar2000 can get the image.)

Usually image is in 'Front Cover' (the first line in table) and MetadataGod.getMetadata() works well, but unfortunately, I have many music files only in 'Disc' position.
I didn't learn rust so I can't pull any requests now.

Demo mp3 file to reproduce is in the zip file.
ape-id3v2.zip

2. Is there any plan to fetch lyrics and sample rate?

Environment:

• OS: Android 12
• flutter version: 3.3.2
• metadata_god version: 0.3.1

The rust plugin only reads the very first Image metadata although it can read from that position but doesn't do it to maintain a Uniform interface for all audio file's metadata
So give me some time to find the possible solution for these
