Add Logger.withMetadata() function to create a logger with multiple metadata values

[gabbifish]

Expected behavior

Let’s say I have an existing Logger.Metadata struct I want to add to a Logger as metadata. It doesn’t seem like there is a simple function like Logger.withMetadata(metadata: Logger.Metadata) I can use. This means I have to iterate through every kv pair in my Logger.Metadata and add it to the logger with logger[key] = value, which is verbose.

(this withMetadata pattern is common in many logging libraries, so it would be great to have this as a convenience function in swift-log as well)
