Update Python client to support batch insert and search

[peopleig]

batch_insert() takes a list of (DenseVector, Payload) tuples

batch_search() supports multiple formats of input

• List of SearchQuery objects
• List of (DenseVector, Similarity, Limit) tuples
• List of (DenseVector, Similarity) tuples with a global Limit
• List of (DenseVector, Limit) tuples with a global Similarity
• List of DenseVector with global Similarity and Limit

SearchQuery model introduced because using tuples will get cumbersome if the number of fields in a query were to increase

Very similar to SK1PPR's batch insert and search implementation.
But with slightly stricter checks and multiple input format support. Added tests.

Add this to __all__

Also can we add batch support for the Async client as well?

We can also add a test like:

from vortexdb.client import VortexDB
from vortexdb.async_client import AsyncVortexDB


IGNORED_METHODS = {
    "__enter__",
    "__exit__",
    "__aenter__",
    "__aexit__",
}


def public_methods(cls):
    return {
        name
        for name, value in cls.__dict__.items()
        if callable(value)
        and not name.startswith("_")
        and name not in IGNORED_METHODS
    }


def test_sync_async_client_api_parity():
    sync_methods = public_methods(VortexDB)
    async_methods = public_methods(AsyncVortexDB)

    assert sync_methods == async_methods, (
        "Sync and async clients expose different APIs. "
        f"Only sync: {sorted(sync_methods - async_methods)}. "
        f"Only async: {sorted(async_methods - sync_methods)}."
    )

So that if there's a public api for one it should be present for the other, avoiding drift

Yes, sorry, I forgot to update it here, I was sleepy.
I made a PR which resolves the merge conflicts and also adds batch support to the async client: #85 . We can continue on that one
I'll add the parity check in tests/
