Cleans the output of `getEnviroClimateRange`

At the moment, `getEnviroClimateRange` outputs a bunch of `\t`, `\n` characters and so forth. I just added a `gsub` line in the return to clean it.

**Before**

```
$Cichla_kelberi
[1] "\r\n\t\t\t\t\tFreshwater;  benthopelagic.   Tropical\t\t\t\t"
```

**After**

```
$Cichla_kelberi
[1] "Freshwater;  benthopelagic.   Tropical"
```
