gRPC Metadata Creator Utility

This utility package, `grpc-create-metadata`, provides a straightforward helper function to convert plain JavaScript objects into gRPC `Metadata` instances. It automatically handles type conversion for common primitives like numbers and booleans by calling their `toString()` method, while `Buffer` and `String` values are passed directly. The package is currently at version 4.0.1 and primarily receives updates for dependency maintenance, especially related to its `@grpc/grpc-js` peer dependency. Its core differentiation lies in simplifying the common task of populating `grpc.Metadata` objects, which strictly require string or buffer values, by abstracting the conversion logic, making it easier for developers to work with gRPC services in Node.js. It maintains a stable, albeit infrequent, release cadence driven by underlying gRPC dependency updates and security patches.
