This switches the input parameters for API calls to a generic
keyword argument catch-all which is then loaded into a dataclass
where the parameters are checked and forwarded to internal
function.
The dataclass gives more flexibility with the parameters and makes
it easier to reuse common parameters for the different API calls.
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.
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.
Code is now organized by api version. So formatting has moved to
the api.v1 module. Instead of holding a separate ResultFormatter
object per result format, simply move the functions to the
formater collector and hand in the requested format as a parameter.
Thus reorganized, the api.v1 module can export three simple functions
for result formatting which in turn makes the code that uses
the formatters much simpler.
Use a directory for the submodule where the __init__ file contains
the public API. This makes it easier to separate public interface
from the internal implementation.
Check if the API script exists on the expected location before
running php-cli. This way we can add a useful hint about the
project directory.
Fixes#2513.
