Updates a few issues that can cause bugs in applications or make SDK generation easier
- Removed all default values. These can cause issues in some situations where the API already handles default values. For example the fit crop value should not be the default for HTML assets.
- Removed required values from responses. The updated field can cause issues if the renders table has not yet been updated and the updated column does not exist. Updated, created and a few other fields are not required anyway.
- Allow poster and thumbnail to be null. This causes issues with the Python SDK which didn't know how to handle nulls values in a response.
