gdal raster / vector clip: extract a specific tile

[dbaston]

Feature description

From the user survey:

I'd love it if there was a GDAL command to call for a specific tile from a raster or vector file using a specific tile scheme...I think it'd be a kick-ass feature to have to, if anything, test whether a specific rendered tile is correct.

Additional context

clipping is probably not the appropriate command where this could be implemented as tile extraction may involve reprojection, and in the case of raster resampling.
For raster, this can already be accomplished with gdal raster tile --tiling-scheme=<SCHEME> --min-zoom=<Z> --max-zoom=<Z> --min-x=<X> --max-x<X> --min-y=<Y> --max-y=<Y>

I can see it being used without reprojection / resampling to look at the source data that would be used to generate a specific tile: essentially be a combination of --bbox and --bbox-crs. Maybe --bbox could even recognize something like --bbox WebMercatorQuad:<z>/<x>/<y>.

Maybe not a good idea, and in any case I don't think there's any urgency to this.
