Derive the standard Error trait using the thiserror crate

[therustmonk]

Enhance the Error type by implementing the std::error::Error trait with the aid of the thiserror crate.

This enhancement will streamline the process of integrating this error type with various other error management strategies.

Hi, thanks for the PR! I agree we should implement std::error::Error however personally I think using thiserror is overkill in this situation since the error type is small and we don't have any nested errors where we need to track error sources.

We should just implement Display manually and then implement the default implementation of std::error::Error, like this:

impl std::error::Error for Error {}

It's slightly more boilerplate but it saves us a dependency
