Adapt to msgpack 1.2.0 (#3167) - #3180

#### Reference Issues/PRs
<!--Example: Fixes #1234. See also #3456.-->
Fix `test_deep_nesting_metastruct_size_over_limit` and
`test_deep_nesting_metastruct_size_under_limit`
Culprit: `msgpack 1.2.0` has just released. It includes [Raise
DEFAULT_RECURSE_LIMIT from 511 to 1024 by Copilot · Pull Request #676 ·
msgpack/msgpack-python](msgpack/msgpack-python#676)
which changes `DEFAULT_RECURSE_LIMIT` from 511 to 1024
`python 3.9` is unaffected as the new msgpack version has dropped the
support

#### What does this implement or fix?
Hard-pin the arcticdb limit to `511` as msgpack <1.2.0
#### Any other comments?
msgpack <1.2.0 has the recurse limit set at 511. arcticdb imports the
limit from msgpack to calculate the metastruct layer limit
msgpack 1.2.0 has raised limit from 511 to 1024. Since reconstructing
the metastruct from is done by recursion, increasing the no. of layers
in the metastruct will make arcticdb hit the python recursion limit.
