More Configuration Options for Maps App

[TopHatProductions115new]

Hello, Nextcloud Developers,

I have been using the Nextcloud Maps app for years. It has been useful on many occassions. It has even assisted with real-time navigation, in instances where apps like Google Maps or Apple Maps failed. I eagerly await the update that makes the Maps app compatible with Nextcloud 32.

I recently encountered an issue (after extracting the latest maps for North America), where the Nextcloud Maps app was seemingly rate-limited by Nominatim. From what I've red, their service is being provided free-of-charge. But service hosting isn't free, and many people may be relying on this service. After a few days of tinkering, I ended up making a few minor changes to [AddressService.php]:

        private function lookupAddressExternal($adr): array {
                if (time() - intval($this->memcache->get('lastAddressLookup')) >= 3) {
                        $opts = [
                                'http' => [
                                        'method' => 'GET',
                                        'user_agent' => 'Internal Service Name (powered by Nextcloud)',
                                ]
                        ];
                        $context = stream_context_create($opts);

                        // we get rid of "post office box" field
                        $splitted_adr = explode(';', $adr);
                        if (count($splitted_adr) > 2) {
                                array_shift($splitted_adr);
                        }

                        // remove blank lines (#706)
                        $splitted_adr = array_filter(array_map('trim', $splitted_adr));
                        $query_adr = implode(', ', $splitted_adr);

                        $result_json = @file_get_contents(
                                'https://nominatim.openstreetmap.org/search.php?q=' . urlencode($query_adr) . '&format=jsonv2&email=admin@mail.txp-network.ml',
                                false,
                                $context
                        );

I'm not a developer, and these are not major changes. But this did seem to fix the issue I was having.

Would it be possible to make the changed variables configurable via the web UI?
