feat: add noMoveStart prop to LMap

[Kapcash]

I need to use the noMoveStart option from leaflet to avoid triggering movestart events when the map auto pans.

This PR only adds a new prop to LMap.vue to specify this option. I named it noMoveStartOnPanning because I think noMoveStart can be a confusing name (can be understood like "don't even fire the moveStart event which is obviously not the purpose of the prop).
