Update fakeredis dependency to main repo (#179)

Nate's PR fixing xpending_range has been merged into the main fakeredis
repo, so we can now switch from his fork to the official repository.

## Changes

- Moved fakeredis from dev dependencies to main dependencies (it's used
for the memory backend feature, not just testing)
- Updated from Nate's fork to main repo at commit ad50a0d
- This commit includes the xpending_range fix that returns all 4
required fields (message_id, consumer, time_since_delivered,
times_delivered)
- Added comment noting we're using a specific commit until version >
2.32.0 is released (presumably 2.33.0)

## Testing

Verified with full test suite using memory backend - all 272 tests pass,
including the 4 memory backend specific tests.
