Remove serialization/enableable

Currently working on an EPEE [ser/de]ialization library for Rust and at first glance, EPEE seemed to have support for optional wrappers. However, after looking into it, this feature appears to be half-baked and unused. Furthermore, adding support for optional values would be better suited to implement at the storage level, in my opinion. That would make parsing DOMs easier and less error-prone. If anyone is currently using this code, please comment. Thanks!
