feat: Add support for Leaflet.PolylineDecorator

[amplitudesxd]

The following leaflet plug-in is helpful, https://github.com/bbecquet/Leaflet.PolylineDecorator - would be great if it could be supported by this module.

Seems cool !

There's no update for 7 years so I'll first have to check if it still works correctly with recent tools and environments.
Leaflet is a capricious library sometimes lol

Thanks for the issue 👍

@Gugustinette haha, no worries - thanks a lot :) I've been using it for a while in my Nuxt site and haven't found any issues, so seems to be working pretty well with modern tooling
