Disable serialization and unserialization on classes (#105)

Browse Source 
* Disable serialization and unserialization on classes

Classes that have associated Rust types cannot be serialized for
obvious reasons so these need to be disabled. Disabling these actions
changes in PHP 8.1 to use a flag, so that will need to be solved with
PHP 8.1 support. Closes #97

* update docs stubs
