RoR2: 1.20 content update (#1396)

## Adding in Explore Mode:

Features include:
* Added in `environments` to be items.
* `Location checks` are now `environment based` instead of being able to get them from anywhere.
* Added in support for the `DLC Survivors of the void` which include `Void Items` and `3 new maps` that come with it. (option added to use DLC)
