Regenerate SpacetimeDB ClientAPI bindings

Description of Changes

Describe what has been changed, any new features or bug fixes

Staging has been broken in Unity since this PR merged: https://github.com/clockworklabs/com.clockworklabs.spacetimedbsdk/pull/116

The errors:

C:\Users\lightfox\lightfox\com.clockworklabs.spacetimedbsdk\src\Primitives.cs(79,35): error CS0426: The type name 'U128' does not exist in the type 'AlgebraicType'
C:\Users\lightfox\lightfox\com.clockworklabs.spacetimedbsdk\src\Primitives.cs(42,35): error CS0426: The type name 'I128' does not exist in the type 'AlgebraicType'

I believe the reason for this is out of date bindings for the ClientAPI. I've regenerated the bindings and it seems to be building now.

This must go into 0.12, without this PR this sdk doesn't build in Unity!
