Simple hugo deploy script to S3 bucket

deploy.sh

## This used to be the way I deploy ... 
## aws --profile=san-study s3 cp ./public/ s3://jeremyandjames/ --recursive
## Now I use this simple script to increamentally update a hugo site on s3 bucket. It is a whole lot faster and take less bandwidth ;)
## Note that the change base on size of the file, not hash because it's quicker to just get the size :p
## Uncomment aws copy and remove command to start using it ;)
