Heic image converter lambda (#108)

* Add image converter lambda js file

* Update to add delete of original file, some checks for file responses, and comments

* add image converter lambda name to main.tf script for the wfdm file index initializer, add a call to the file index initializer to call the image conversion lambda for heic files

* Remove commented out code

* Change access of fileId from event since the lambda is no longer pulling from a queue

* remove delete from file conversion lambda as the file will now be replacing itself as a version update once the API is updated

* Adding notifier if image conversion is attempted or aborterd due to file size

* Update to ensure file conversion field is only set when conversion is attempted
