Hashes prevent returning results

## Reproducible Example

It appears that a hash (`#`) in the query of `ggmap::geocode()` will prevent returning a result. Perhaps queries should be cleaned? Below I use the same address but switch the `#` with "Suite" and it works fine.

```
> ggmap::geocode("110 Channel St #1 94158")
Source : https://maps.googleapis.com/maps/api/geocode/json?address=110+Channel+St+#1+94158&key=xxx
Warning: Geocoding "110 Channel St #1..." failed with error:

# A tibble: 1 x 2

1 NA NA
> ggmap::geocode("110 Channel St Suite 1 94158")
Source : https://maps.googleapis.com/maps/api/geocode/json?address=110+Channel+St+Suite+1+94158&key=xxx
# A tibble: 1 x 2

1 -122. 37.8
```

For now a simple `gsub()` appears to be the easiest workaround. For example:
`gsub("\\s#", " Suite ", "110 Channel St #1 94158)`
