How to reproduce:
1. Create a new Unity project and import the 2D PSD Importer package
2. Download the user-supplied "error.psb" file
3. Import the file to your Unity project

Expected result: the .psb is imported successfully
Actual result: errors appear in the Console upon trying to import

Reproducible with:
1. 2.0.3 (Unity 2019.3.0a12)
2. 2.1.3 (Unity 2019.3.8f1)
3. 3.1.1 (Unity 2020.1.0b4)
4. 3.1.3 (Unity 2020.2.0a5)

Could not test with: 2017.4 (due to the missing package), 2018.4 (2D PSD Importer unavailable)
