This Constructor Doesn't Return a Class Instance

	@classmethod
	def mainnet(cls) -> Type["LakeConfig"]:
	cls.s3_bucket_name = "near-lake-data-mainnet"
	cls.s3_region_name = "eu-central-1"
	return cls
	@classmethod
	def testnet(cls) -> Type["LakeConfig"]:
	cls.s3_bucket_name = "near-lake-data-testnet"
	cls.s3_region_name = "eu-central-1"
	return cls

While testing #9, the type checker has correctly pointed out that this isn't really a constructor. Since the project is still released below v1, I think its reasonable to change the constructor interface. I will make a proposal for this in the open PR related to types.
