+-

+- [x] Pass --message as file (use the '@' like `--message "@<filename>"` format to determine if its a file or not like `curl --data-binary` of `--message fileb://<filename>` like lambda
+- [ ] Add more event types (SNS, S3, Dynamo, API Gateway, IoT)
+  - [x] Cloudwatch Log
+  - [ ] Cloudwatch
+  - [ ] SNS
+  - [ ] S3
+  - [ ] Dynamo
+  - [ ] API Gateway
