FloatImage not working in folium v0.13.0

[giswqs]

Describe the bug
FloatImage does not work properly in folium v0.13.0. The image appears to be enlarged many times.

To Reproduce

import folium
from folium.plugins import FloatImage
import base64

m = folium.Map()
image = 'LmTETPX.png'  # downloaded from 'https://i.imgur.com/LmTETPX.png'
with open(image, "rb") as lf:
    b64_content = base64.b64encode(lf.read()).decode("utf-8")
    widget = FloatImage(
        "data:image/png;base64,{}".format(b64_content),
        bottom=50,
        left=75,
    )
widget.add_to(m)
m

Directly passing the image path does not work either.

m = folium.Map()
image = 'LmTETPX.png'  # downloaded from 'https://i.imgur.com/LmTETPX.png'
FloatImage(image, bottom=50, left=75).add_to(m)
m

Expected behavior

It works as expected in folium v0.12.1.post1

Environment (please complete the following information):

• Browser: chrome
• Jupyter Notebook
• Python version: 3.9
• folium version: 0.13.0
• branca version: 0.4.2

Thanks for the report! I can confirm the issue. This is very likely because of #1570. I think the fix is simple: make width an optional parameter. I'll open a PR.
