Nutype 0.5.1 - enhanced no_std support and bug fixes

I am excited to announce the release of Nutype 0.5.1, which brings some fixes for an improved developer experience. Below is an overview of what's included in this version:

🚀 New Features

• no_std Support for ::core::error::Error
  Nutype now generates an implementation of ::core::error::Error in no_std environments when using Rust version 1.81 or higher. This enhancement ensures better compatibility with modern Rust ecosystems.

🛠️ Bug Fixes

• Custom Error Paths
  You can now specify custom errors using a path, providing greater flexibility for your error-handling needs.
  (#186, #187)

• Deserialize Derive Compatibility
  Resolved an issue where deriving Deserialize caused compilation errors when using both no_std and serde features.
  (#182)

• Lint Warnings
  Fixed unnecessary lint warnings related to the inner generated module for cleaner builds.

• Conflict with borsch Crate
  Addressed a conflict with the borsch crate to ensure seamless integration.
