Banner textures are not located in an optimal or intuative file path for resource pack creators

There are two primary issues here:

1. The texture (banner_base.png) is stored inside (...\textures\entity) instead of being stored inside (...\textures\entity\banner) with all the other banner related textures.

2. All the banner patterns are stored inside (...\textures\entity\banner) together, instead of having their own sub-folder inside (...\textures\entity\banner). This is unusual when compared to the storage of other entity's textures like the villager, whose (profession), (profession_level), and (type) are all stored seperately inside the (...\textures\entity\villager) folder for optimal clarity.

Steps to Reproduce:

1. Go to the following file path:
   C:\Users[user]\AppData\Roaming\.minecraft\versions[latest_version]

2. Right click the [version].jar] file, and open it in a file explorer (like 7zip or winrar)

3. Go to the following path inside the jar:
   assets\minecraft\textures\entity

Suggested Fix:

Add a sub-folder called (banner_patterns) or even just (patterns) (to avoid redundancy) inside (assets\minecraft\textures\entity\banner), where all of the banner patterns will be put, and then move (banner_base.png) into (assets\minecraft\textures\entity\banner). This will provide optimal clarity to the player who is trying to explore the files to make a resource pack.

The end result would be this:
