Out of Memory when browsing photos in large folder

### ⚠️ Before posting ⚠️

- [x] This is a **bug**, not a question or an enhancement.
- [x] I've [searched for similar issues](https://github.com/nextcloud/android/issues) and didn't find a duplicate.
- [x] I've written a clear and descriptive title for this issue, not just "Bug" or "Crash".
- [x] I agree to follow Nextcloud's [Code of Conduct](https://nextcloud.com/contribute/code-of-conduct/).

### Steps to reproduce

1. Have large folder (12k photos and videos, 40gb)
2. scroll through
3. open a few photos, then go back keep scrolling
4. repeat 3-4 times
5. Out of memory exception

### Expected behaviour

Even though its quite a tough situation with such a big folder, the app should make it work without throwing a hard OOM error. Like free up memory from previously watched content.

### Actual behaviour

### Cause of error
```java
Exception in thread "Thread-42" java.lang.OutOfMemoryError: Failed to allocate a 52696 byte allocation with 1436800 free bytes and 1403KB until OOM, target footprint 268435456, growth limit 268435456; giving up on allocation because <1% of heap free after GC.
