Out of memory error when selecting item

A small percentage of my users are getting the following error:

```
Fatal Exception: java.lang.OutOfMemoryError
android.graphics.BitmapFactory.nativeDecodeAsset (BitmapFactory.java)
android.support.v4.content.ContextCompat.getDrawable (SourceFile:374)
com.aurelhubert.ahbottomnavigation.AHBottomNavigationItem.getDrawable (SourceFile:133)
com.aurelhubert.ahbottomnavigation.AHBottomNavigation.updateSmallItems (SourceFile:752)
com.aurelhubert.ahbottomnavigation.AHBottomNavigation.setCurrentItem (SourceFile:1149)
com.aurelhubert.ahbottomnavigation.AHBottomNavigation.setCurrentItem (SourceFile:1130)
```

I'm using SVGs for my icons. Also, I'm using the 2.0.4 version of this library.

I haven't been able to reproduce the issue so I'm wondering if anyone else has encountered this issue?

The report points to AHBottomNavigationItem.getDrawable, AHBottomNavigation.updateSmallItems, and AHBottomNavigation.setCurrentItem, with SVG icons and library version 2.0.4 involved. Start by reviewing those stack-trace entry points and the SVG setup; no reproduction steps, target file, test, or acceptance condition is provided.
