Add additional parameters for folium layer

[giswqs]

I am excited for find this package! Nice work. This PR adds kwargs to the __init__ so that it can accept other folium layer paramters, such as overlay. Putting overlay in options has not effect.

BTW, the PMTiles has a large gray background on the top of other layers. Can it be made transprant?

import folium
from folium_pmtiles.vector import PMTilesVectorBaseMap

m = folium.Map(location=[43.7798, 11.24148], zoom_start=12)
pmtiles_layer = PMTilesVectorBaseMap(
    "https://pmtiles.jtmiclat.me/protomaps(vector)ODbL_firenze.pmtiles",
    "PMtiles",
    options={
        "attribution": """<a href="https://protomaps.com">Protomaps</a> © <a href="https://openstreetmap.org/copyright">OpenStreetMap</a>'"""
    },
    overlay=True,
)
m.add_child(pmtiles_layer)
folium.LayerControl().add_to(m)
m

Looks good. Pushed a small commit that runs black formatter on the files.

Awesome! Thank you. It would be a game changer if we can also add support for ipyleaflet. Your contributions would be greatly appreciated.

I'm not to familiar with ipyleaflet but I can take a look in the next couple of weeks!

[giswqs]

That would be great. Thank you.
