Display (walking) direction/route to a custom markers

Is your feature request related to a problem? Please describe.

I'm working on creating a map which has ability to show current location (already done using LocateControl plugin) and has custom markers. I would like to be able to show (walking) route to custom markers from my current location.

Going through bug reports, I found similar request in #484, but in my case it's definitely not solved as part of #669

Describe the solution you'd like

I would like to be able to use plugins such as:

• Leaflet Routing Machine
• Leaflet.Routing

as pointed on Leaflet Routing plugins list

Describe alternatives you've considered

From my current research alternative would be to use different library/backend with Google Maps, but unfortunately there isn't a lot of information on this either.

Additional context

Functionality I would like to achieve

Implementation
folium is maintained by volunteers. Can you help make a PR if we want to implement this feature?

If the time allows yes.

Überprüfe die verwandten Issues #484 und #669 und untersuche anschließend die in der Anfrage verlinkten Plugins Leaflet Routing Machine und Leaflet.Routing. Lege fest, wie ein aktueller Standort und ein benutzerdefinierter Marker mit einer Fußgängerroute verbunden werden sollen, einschließlich der Integrationsgrenze zwischen folium und Leaflet; die Funktion ist abgeschlossen, wenn Benutzer diese Route zu einem ausgewählten benutzerdefinierten Marker anzeigen können.
