add `/map` prefix to tiles endpoint

right now we have tiles endpoints in form of `/tiles/{tileMatrixSetId}/{z}/{x}/{y}` which is compliant with OGC Tileset specification.

we could also comply with `dataset-tileset` and `tilesets-map` conformance by adding `/map` prefix to the /tiles endpoints

```
# now
../tiles
../tiles/{tileMatrixSetId}
../tiles/{tileMatrixSetId}/{z}/{x}/{y}[@{scale}x][.{format}]
/tileMatrixSets
/tileMatrixSets/{tileMatrixSetId}
