TMS/XYZ fails if non-default bounds are set in tile.json.

[grantporterdg]

Using a tile.json with "bounds" such as:

{
    "tiles": "https://s3.amazonaws.com/deepcore-public/images/ATL_TMS/{z}/{x}/{y}.png",
    "name": "ATL_Airport_Tiles",
    "minzoom": "17",
    "maxzoom": "19",
    "tilejson": "2.1.0",
    "scheme": "tms",
    "bounds": [ -84.44117546081544, 33.63652538928871, -84.42211924272648, 33.64431470837889 ]
}

When it is used for detection with the following command:

        ../bin/OpenSpaceNet detect --service tile-json --use-tiles
        --url https://s3.amazonaws.com/deepcore-public/images/ATL_TMS/tile.json
        --output tms_nofilter/detection.shp
        --bbox -84.44117546081544 33.63652538928871 -84.42211924272648 33.64431470837889
        --zoom 18 --model ../data/airplane.gbdxm

You get: 404 Not Found returned from https://s3.amazonaws.com/deepcore-public/images/ATL_TMS/18/13/262137.png

It is trying to access a tile that is wrong and does not exist.
