* Fix for distance
Fixes the `distance` to search not being passed through to `ImageReverse.images()`
`set_scraper_cache` passes the `distance` through into `params`
`create` normalizes and inserts the result into the params passed to `ImageReverse.images()`
`normalize_dist` checks if there is a `distance` set, adds a leading 0 to it (to account for values like `.5`, which would crash `Float.parse()`), and turns it back into a well-formatted string for `ImageReverse.images()`
* Fixed space
