The initial plan to serve /details and /lookup endpoints from
the same API call turned out to be impractical, so the API now
also has deparate functions for both.
Prepared statements do not work well with the partial indexes that
Nominatim uses because all Python constants are replaced with
parameters. A query like:
placex.select().where(placex.c.rank_address.between(4, 25)
gets translated into a prepared query with two parameters:
SELECT * FROM placex WHERE rank_address BETWEEN %s and %s
And this does not work with a partial index of:
CREATE INDEX on placex(geometry) WHERE rank_address between 4 and 25
The only allowable difference is precision of coordinates. Python uses
a precision of 7 digits where possible, which corresponds to the
precision of OSM data.
Also fixes some smaller bugs found by the BDD tests.
The implementation follows for most part the PHP code but introduces an
additional layer parameter with which the kind of places to be returned
can be restricted. This replaces the hard-coded exclusion lists.
Use adapted types for the different result types. This makes it
easier to have adapted output formatting and means there are only
result fields that are filled.

This reverts commit 6839eea755a87f557895f30524fb5c03dd983d60.
added default parameters and refactored code
added test for all parameters
Add a special index that contains the place nodes buffered by their
respective area according to their search rank. This replaces the
maximum area search for place nodes and reduces drastically the number
of place nodes that need to be retrieved.
It is not possible to produce type annotations that work with both
versions 1.4 and 2.0. So keep to the principle of only supporting
newest versions when it comes to mypy. This means that some types
may have to be string quoted to not cause issues when running with
SQLAlchemy 1.4.
Also defines an extended connection object that includes access to
the table definitions. Makes it easier to access the tables from
code that has been split off into separate modules.
