When installing 2D Animation package version 3.0.0, the Editor yields these Errors:
Library/PackageCache/com.unity.2d.common@2.0.0/Runtime/InternalBridge/InternalEngineBridge.cs(10,28): error CS1061: 'SpriteRenderer' does not contain a definition for 'SetLocalAABB' and no accessible extension method 'SetLocalAABB' accepting a first argument of type 'SpriteRenderer' could be found (are you missing a using directive or an assembly reference?)

and

Library/PackageCache/com.unity.2d.common@2.0.0/Runtime/InternalBridge/InternalEngineBridge.cs(15,28): error CS1061: 'SpriteRenderer' does not contain a definition for 'SetDeformableBuffer' and no accessible extension method 'SetDeformableBuffer' accepting a first argument of type 'SpriteRenderer' could be found (are you missing a using directive or an assembly reference?)

These errors keep the project from entering play mode and makes the package unusable.

To reproduce
- start a new project
- install 2D Animation version 3.0.0

Reproducible in 2019.3
