Render map as static HTML file

[kylebarron]

Closes #473

import lonboard
import geopandas as gpd

gdf = gpd.read_file(gpd.datasets.get_path('nybb'))

m = lonboard.viz(gdf)
m.as_html()

Just tried this @kylebarron but as_html() doesn't work in a jupyter notebook.. I've got lonboard 0.8.0 installed via poetry with geopandas 0.14.3.
