unwrap_or_log

This crate adds functions to all [std::results::Result<T,E>] where E implements [std::error::Error] by implementing the trait [Loggable<T>] for them

The trait [Loggable<T>] exposes three functions:

• unwrap_or_log: Returns the contained value [T] or logs the error and panics
• log_if_error: Log the error and returns itself
• ok_or_log: Converts [std::result::Result<T, E>] to an [Option<T>] and logs the error if present
