geojsonFolder with relative Path to the Markdown *.md File

[SpocWeb]

Hi, I love the geojsonFolder Feature.
But it seems to search all *.geojson Files based on the Path to the Obsidian Vault Directory, not the Path to the actual Markdown File.
I think this would be a good feature, since most geographical Features are stored in a hierarchical order by Continent, Country, State, City etc.

To illustrate this:

I have a File named Aland.md and a Folder named Aland next to it (in the same Super-Folder)

In the Aland.md I have the following Section:
```leaflet
id: Åland
zoomFeatures: true
geojsonFolder: ./Åland
```

But when opening the File in Obsidian, the leaflet Plugin takes a long time and displays ALL *.geojson Files I have in my Vault (several Thousands)

I would like to pick up only those in the relative Subfolder of the *.md File.

I'm new to JavaScript/TypeScript development but if You are too busy, would you accept a Pull Request to change this behavior?
Best Regards...

I think it would be good to have an additional Switch or Drowpdown in the Configuration to limit the recursion Depth of the File Search.

I think it should be rather simple to get the Path to the current File and concatenate that with the relative Path/URL entered.
If someone could point me to the right API Function I can try doing this myself.

I have created a Pull-Request with these 2 Features:

• allow for configurable Recursion Depth by appending multiple / (Slashes)
• allow for relative Paths

Hope you will consider merging this into this repository, because leaflet becomes very slow with increasing number of Geometries and recursing arbitarily deep can easily freeze the whole Application!
