This extends the `__rand_int__` pattern to add `__rand_1st__` through
`__rand_9th__`.
For the new placeholders, multiple occurrences within a command will
have the same value.
With the `--sequential` option, each placeholder will use separate
counters.
For `__rand_int__`, the behavior is unchanged - multiple occurrences of
the pattern within a command will have different values.
Examples of using the `__rand_int__` with `--sequential`:
```
$ ./valkey-benchmark -r 300 -n 300 --sequential -q -- set key__rand_int__ val__rand_int__
set key__rand_int__ val__rand_int__: 60000.00 requests per second, p50=0.391 msec
$ ./valkey-cli info keyspace
# Keyspace
db0:keys=150,expires=0,avg_ttl=0
$ ./valkey-cli get key000000000050
"val000000000051"
```
For the new patterns, multiple occurrences within the command will have
the same value.
```
$ ./valkey-benchmark -r 300 -n 300 --sequential -q -- set key__rand_1st__ val__rand_1st__
set key__rand_int__ val__rand_int1_: 60000.00 requests per second, p50=0.383 msec
$ ./valkey-cli info keyspace
# Keyspace
db0:keys=300,expires=0,avg_ttl=0
$ ./valkey-cli get key000000000050
"val000000000050"
```
I also fixed the zadd benchmark so it produces the expected number of
keys when used with `--sequential`. (By using the same counter twice per
command it was effectively counting by twos)
I made this for myself but raised a PR in case y'all like it. 🙂

Introduce a `size_t` field into the rax struct to track allocation size.
Update the allocation size on rax insert and deletes.
Return the allocation size when `raxAllocSize` is called.
This size tracking is now used in MEMORY USAGE and MEMORY STATS in place
of the previous method based on sampling.
The module API allows to create sorted dictionaries, which are backed by
rax. Users now also get precise memory allocation for them (through
`ValkeyModule_MallocSizeDict`).
Fixes#677.
For the release notes:
* MEMORY USAGE and MEMORY STATS are now exact for streams, rather than
based on sampling.
