feat: Implement replies count detection for submissions

[FoxxMD]

Work for #8

[FoxxMD]

Notes:

• Sticked comment is always first returned comment for submission (depth 0) regardless of sort order
• Comment tree context and replies are ONLY initially hydrated if picked from fetched submissions
  • When fetching a single comment (getComment('asdf')) snoowrap uses /api/info which DOES NOT return:
  • depth
  • replies

This is a big issue since we cannot check comment depth, number of replies, or contents of any replies unless we make an additional api call. And even with the additional call we still do not know what depth the original comment was at. Need to take a look at what PRAW is doing for refresh to get additional information.
