mapbox fails with `\t` or `\n` in address

[LukasWallrich]

When I use mapbox, the following gives an Error in curl::curl_fetch_memory(url, handle = handle) : URL using bad/illegal format or missing URL

tidygeocoder::geo(address = "Department \n Marburg", method = "mapbox")

I think this is because the address is inserted into the URL for mapbox, and api_url_modification() does rather little escaping. Maybe that could be made more robust?

Thanks, yes I think that's the issue as "\\n" in the address doesn't cause issues. One potential solution would be to replace lone \ characters with \\.
