This is one part of #38, specifically using the shared ticked instead of bind_table in the case of pydeephaven tables

Requires deephaven/web-client-ui#2189

Tested with the following code

from deephaven_server import Server
s = Server(port=10000, jvm_args=["-Xmx10g", "-DAuthHandlers=io.deephaven.auth.AnonymousAuthenticationHandler"])
s.start()
from pydeephaven.session import SharedTicket
from pydeephaven import Session
from deephaven_ipywidgets import DeephavenWidget

client_session = Session()
table_ref = client_session.time_table("PT1s").update(["X = i", "Y = X / 2"])

DeephavenWidget(table_ref)

server_url, token = _check_session(session, params)

session.bind_table(object_id, deephaven_object)
ticket = SharedTicket(b"h/" + object_id.encode("utf-8"))

What is this magic h/ in front?

Also - does this still only work with tables? We can't publish other kinds of tickets?

I'm not entirely sure myself, I saw you made this comment deephaven/deephaven-core#5854 (comment) so I included it

And this doesn't work for other tickets at this time. I think that requires some other mechanism that we either don't have or is tricky to do. I tried using publish (see implementation of publish_table) but it requires a ticket to already be attached to the object. I didn't really investigate beyond that because it seems like something that requires more careful thought. There is some discussion on #38 for this
