add "SNR" field for MLy
Add an SNR
field for MLy
events as requested by @vasileios.skliris over Mattermost. Example data files are already being uploaded to playground (example).
After the model change and migration, then translator.py
needs to get edited to read in the field from the json upload, then change the view template so it shows up in the page table, and then view_utils.py
so it shows up in the httpresponse and igwn-alert.
