feat(icons): Add Varlamore Part 2 Icons

[nmesot]

This PR adds the new icons from Varlamore part 2.

It took me a while to understand how they are resized properly, but I think I got it right.

It also fixes an issue with the unknown icon from my previous PR, which was not resized properly.

I created a script to download, resize and base64 encode new icons. It is not part of this PR, but I can share that too if interested.

I've been procrastinating doing this so thank you, I'll give it a look and merge if everything looks ok. I also use a python script to generate the icons. Probably should have included that in here from the start, but if yours does the same as mine it should be fine.

Here's my script if you wanted to take a look. I'll add it to the repo as well

import base64
import io
import json
import os

from PIL import Image

ICONS_DIR = 'original'
OUT_DIR = 'out'
OUT_FILE = 'resized.json'

DEFAULT_WIDTH = 36
DEFAULT_HEIGHT = 32

def main() -> None:
    processed = {}

    # Pull files from dir and convert to base64
    for filename in os.listdir(ICONS_DIR):
        filepath = os.path.join(ICONS_DIR, filename)

        with open(filepath, 'rb') as fp:
            img = Image.open(fp)
            processed[filename[:-4]] = process_img(img)

    # Save base64 strings in json file
    with open(os.path.join(OUT_DIR, OUT_FILE), 'w') as fp:
        json.dump(processed, fp, indent=2)

def resize_img(img: Image) -> Image:
    """Resize image to default width and height of 36x32
       This does not resize the image, but creates a canvas
       of the disired width and places the image in the center of
       the canvas

    Args:
        img (Image): Image to resize

    Returns:
        Image: Resized image
    """
    width, height = img.size
    left = (DEFAULT_WIDTH - width) // 2
    top = (DEFAULT_HEIGHT - height) // 2

    resized = Image.new('RGBA', (DEFAULT_WIDTH, DEFAULT_HEIGHT), (0, 0, 0, 0))
    resized.paste(img, (left, top))

    return resized

def img_to_base64(img: Image) -> str:
    """Encode an image in base64 format

    Args:
        img (Image): Image to convert

    Returns:
        str: Base64 encoded image in string format
    """
    bytes = io.BytesIO()
    img.save(bytes, format='PNG')
    return base64.b64encode(bytes.getvalue()).decode('utf-8')

def process_img(img: Image) -> str:
    """Resize and convert image to base64 encoded string

    Args:
        img (Image): Image to process

    Returns:
        str: Base64 encoded image in string format

    resized = resize_img(img)
    return img_to_base64(resized)

    main()

Sweet, I think I my script does the same thing! It's a bit hackier than yours, and written in bash, but here it goes
