Instructions on Timber.io fail when existing lambda provider's default region is not us-east-1

[giodamelio]

I plugged in the timber terraform module and it complained that the lambdas source S3 bucket is in a different region

Error: Error creating Lambda function: InvalidParameterValueException: Error occurred while GetObject. S3 Error Code: PermanentRedirect. S3 Error Message: The bucket is in this region: us-east-1. Please use this region to retry the request

I was able to bypass the problem (I think) by creating a new provider and passing it into the module explicitly. It would be nice if the docs mention the possibility of needing to do this.
