[PLM] Disc shaped area lights do not work in some instances
Steps to reproduce:
1. Download SephoraChristmas project
2. Additively load SephoraForest-Environment and SephoraForest-Lighting scenes
3. Select any area light in the scene
4. Change its shape from Rectangle to Disc
5. Bake the lighting
6. Notice how it is not affecting the lightmap
Notes:
- Affects both CPU and GPU PLM
- This issue is very difficult to reproduce; it only reproduces in a handful of projects under unclear circumstances
- Issue reproduces both when creating new disc lights, and when converting existing ones
- Area light icon disappears after switching to disc light and rebaking (does not reproduce in 2021.1)
- Tested using the following Unity versions: 2019.4.1f1, 2019.4.9f1, 2020.1.12f1, 2020.2.0b10, 2021.1.0a3

Resolution Note (2021.1.X):
The issue was with the ExtractFalloff.cs script. Disc lights were not defined within the switch statement, causing them to break.
