Summary Table: chat_postMessage vs chat_postEphemeral

[jamestiotio]

Might want to reconsider between chat_postMessage and chat_postEphemeral (with each of their own pros and cons) for the summary table:

wthslack/app/handlers/viewing/summary.py

Lines 91 to 94 in 453188d

	# Send scoreboard message
	config.web_client.chat_postMessage(
	channel=channel, user=user_id, blocks=content
	)

For future reference, chat_postMessage would restrict the respective judges to ask for their summary tables in direct messages only, while chat_postEphemeral would restrict too much interaction between the judge and the summary table message since there is no message persistence.
