Bug: object and array params not supported?

[sdebionne]

Describe the bug

When using a dict in the rpc params, the server returns {'jsonrpc': '2.0', 'id': 35342, 'error': {'code': -32602, 'message': 'Invalid method param(s).'}}.

Steps to reproduce

File server.py:

from ucall.posix import Server

server = Server(
    port=8545,
)

@server
def foo(person: dict):
    print(f"[RCV] prepare {person=}", flush=True)

server.run()

File client.py:

from ucall.client import Client

params = {
    "firstname": "John",
    "lastname": "Doe",
}

client = Client(port=8545)

res = client.foo(person=params)
print(f"[CLIENT] client.foo returned {res.data=}", flush=True)

Expected behavior

Should serialize/deserialize the dict from/to JSON.

Yes, such arguments are not supported in v0, but will be in v1.

I found this project that provides a python binding for simdjson: https://github.com/TkTech/pysimdjson
If it works as advertised, that means not much work (or even simplification) should be necessary to support the full JSON data model.
