Remove collection.group()

The same functionality can be achieved using the aggregation pipeline's $group operator.

Db name in the connection string

On this PR, dbName is not inferred from the connection string. Use the dbName option.

Old:

mongoist('localhost:27017/test')

New:

mongoist('localhost:27017', { 'dbName': 'test' })

Major changes

• collection.count now uses countDocuments instead of cursor.count.
• collection.mapReduce is deprecated. Kept for compatibility.
• collection.update and collection.remove returns additional info. "n" and "ok" are deprecated.
• cursor.count is deprecated. Kept for compatibility.

Hey @bradvogel, can you approve the PR's workflow?

Maybe we close this in favor of https://github.com/mongoist/mongoist/pull/97 and future work we will do in order to get support of MongoDB 6.0
