Build the tippecanoe layer (binary)

1. On an AWS Linux 2 instance or image:

   sudo yum update sudo yum install git clang sqlite-devel zlib-devel

2. Create a ZIP archive with the tippecanoe binary at bin/tippecanoe and upload as a Lambda layer

3. Copy lambda_function.py (python 3.9 runtime)

4. set the environment variable OUTPUT_BUCKET to your output bucket; give lambda IAM role access to input/output buckets

5. Enable ACLs on the output bucket
