Add a sort option to 'scope events'

[seanvaleo]

When the scope events command is run, events are displayed in the order in which they are flushed to disk/network, which isn't always entirely chronological. For example, console events are cached for 2 seconds before being written to the events.json file.

We should add a sort option to the scope events command in the cli to improve UX.

QA INSTRUCTIONS

Part 1
Do:

docker run --rm -it cribl/scope:<VERSION_ID>
apt update
apt install curl -y
scope curl wttr.in
scope events
scope events --sort _time
scope events --sort _time --reverse
scope events --sort source
scope events --sort sourcetype --reverse
scope events --sort nonexisting
# etc...

Expect:
You are able to sort on any valid event body field name. View the json output with scope events -j to see field names.

I bugathoned this with v1.0.2-rc0 on 10-Mar-2022. Looks great!
