Just place this file in ~/.local/share/harbour-poor-maps/tilesources. That directory doesn't exist by default, but you can just create it.

Since Poor Maps 0.16, you can try

    "scale": 0.5,
    "smooth": true,

in there if the font seems big. This will quadruple your data traffic, so expect the map to load slower.

Updated. @1x and @2x versions to match current naming and related filters in Poor Maps.
