Please add Server-Send-Events on changes to the json data

[Alex-Jongman]

Would be nice if the json-server would offer server-send-events when data gets created, modified or deleted.
Front-ends then could use EventSource to get notified and can react on the changes.

@Alex-Jongman I had a use for this and created a PR for this here

@ikeohachidi thanks for the info. I tried you PR, unfortunately it didn't fulfill my needs.
But it gave me inspiration to create a fork myself (see here).
Hope that the SSE feature to prevent clients from have to use active polling, to determine changes in the data will make it to the main branch.
