Parse Slack message history into Fountain (basic)

Slack exports: https://get.slack.help/hc/en-us/articles/201658943-Export-data-and-message-history

At minimum write a very simple converter for messages to Fountain format (we'll do more complicated work later)

Observations:

• Slack format has a standalone users.json file which contains things like first name / last name which would be handy to use. Not all users have first_name last_name properties, some have real_name (which are sometimes just the nickname).
• Slack does not have gender pronouns (because why would they?) but knowing this would make stage direction and words exist better
• Messages are grouped by channel / day
• Messages are in an ordered array
• Messages have a user (ID keyed to users.json) and a text property. ts for timestamp. In text, referenced @users use <@___ID___> format, these need to be replaced out.
• Messages have a subtype. E.g. subtype: channel_join can be translated to PERSON enters.

@slifty Can you do a dump of channel history at https://thegpf.slack.com/services/export? And choose a small subset of chats to do a first pass on.

Yes -- but I'll be making sure we have permission from folks involved in whatever the channel is!
