Redistimeseries

- 918 Avoid possible arithmetic overflow in `avg` aggregation.
- 995 [RESTORE](https://redis.io/commands/RESTORE) now updates the series internal stored key name, to handle restore with a different name.

**Notes:**

- This is the first GA version of 1.6. The version inside Redis will be 1.6.8 in semantic versioning. Since the version of a module in Redis is numeric, we could not add a GA flag.
- Minimal Redis version: 6.2

- 941 Added assertion: chunk_size must be a multiplication of 8
- 933 Fixed ts.del iterator
- 932 Fixed open key with write permission was missing in some places
- 931 Fixed save/load duplicatePolicy in RDB
- 902 Fixed memory leak in ts.del flow
- 891, 892 Fixed memory leak in parseCreateArgs when parsing error occurs
- 862 Index dictionary is now freed when removing the last element
- 881 MADD: only the successful insertions are replicated

**Notes:**
- The version inside Redis will be 1.6.3 in semantic versioning. Since the version of a module in Redis is numeric, we could not add a Release Candidate flag. The GA version will follow soon.
