Adds a new extension accordian titled "Extra Samplers" to allow adjusting certain samplers.

## Installation

### Clone from Git

1. Navigate to the extension directory in your WebUI installation
1. Clone the repository:
    ```sh
    git clone https://github.com/MisterChief95/sd-forge-extra-samplers.git
    ```
1. Start WebUI

### Install from URL

1. Open the Extensions tab in the web UI.
2. Go to the "Install from URL" section.
3. Enter: `https://github.com/MisterChief95/sd-forge-extra-samplers.git` in the "URL for extension's git repository" box.
4. Click "Install".
5. Restart WebUI

## Usage

1. Open the WebUI.
2. Navigate to the sampler settings.
3. Select one of the newly added Euler samplers from the list.
4. Generate images as usual.

### Important
- Not all samplers work well in every situation. Some will look poor when used for img2img/hires fix.
- Mix-and-match samplers to find the best combinations. A sampler might look bad with one scheduler but good with another!
