Use the addr:floor OSM tag when available to get named
floor for places.

Use coordinates to determine country if not set as a
construct parameters, or available via the addr:country
tag. This fixes getting the right address format when
clicking directly on a POI icon on the map when there's
no addr:country tag set, getting the same behavior as
when instanciating the place from a search result
(via the Photon parser).

This allows clicking on icons underneath the accuracy circle.

The code that inserted the highway shields layer worked by finding the
index of the 'road_shield' layer in OSM Liberty, then splicing the
Americana shield layer over it. The new map style doesn't have a
'road_shield' layer though, so findIndex() returned -1, which splice()
interpreted to mean the last item of the list. This happened to delete
the neighborhoods layer.

Fixed by moving the code that inserts the Americana shields layer into
the map style itself, so no splice is needed.

The script exports the map style as JSON and creates a MapLibre GL
JS-based preview page.

Add a script to serve the MapLibre GL JS-based map style preview. When
you edit the map style subdirectory, the style is regenerated and the
page is refreshed.

The MapLibre page doesn't have the shield generator, so just skip that
layer.

This lets us write some of the logic in JS instead of MapLibre
expressions, and it's much more performant since it happens once instead
of every time a symbol is created.

FIx typo in getter determining if the
place is of eating&drinking type that
prevented triggering showing the
takeout information.

Don't use uppercase text transform for
labels for hamlets.

Add some missing icon mappings where we already
have icons:

Bicyle shops
Clothes shops (using the alternative shop=clothes mapping
Miniature golf (using the alternative
leasure=miniature_golf tagging)
Trash cans

As with other similar POIs like recycling.

Since E-mail is British spelling, change
this to be "Email".

Fixes #623

Fixes #624

Also introduce a way for place definitions
to defined a max rank for filtering so
that smaller islands (higher rank) can
be filtered out at lower zoom levels.
And add support for an optional id
to override the autogenerated one
based on classes to allow multiple
place definitions using the same classes
but different parameters, such as maxRank.
This is needed for compatibility with MapLibre.

Appstream decided to use reversed domains. Please merge before 46 if possible.

Use icons for jewelry, hardware shops, and
subway entrances.

Use the text direction when looking up icons. For example, the icon for
train/subway station entrances uses exit-symbolic, which has an rtl
variant. We want the icons to match what people see in the UI.

Made several changes to reduce the number of POIs shown:
- Set padding to 10px
- "text-optional" is false until z18
- At zoom levels 15-17, limit POIs by "rank", which is calculated by
OpenMapTiles for this purpose

That way it doesn't order them differently each time, resulting in
confusing diffs.

If the country code needs to be calculated from the lat/lon, store that
computed value. This saves a small but measurable amount of time on
startup that would be spent instantiating GWeather.Location objects
while loading the place store.
