feat(py/client-ticking): Add support for LocalDate and LocalTime

[kosak]

This PR adds support for LocalDate and LocalTime to pydeephaven/ticking.

Note this PR depends on #6105, so that one should be merged first.

It also depends on #6137, which also needs to be merged first.

I also add a comment to pydeephaven/README.md to remind people to make a venv.

Also note that this is a fix for #6044

The changes LGTM but I'd like to see a simple test case for the new types.

I second @jmao-denver 's comment.

The test looks good. It doesn't need to cover uploading arrow data to the server (doPut). I wonder though if the C++ client needs to support doPut and if that's been tested. I am asking because the R client depends on it.

There are two answers to this question. The first is that if people are using our ColumnSource style interface, then yes, C++ supports that. In our C++ client we have two new types: LocalDate and LocalTime, and we have a test that shows pushing a vector of those to the server: https://github.com/deephaven/deephaven-core/blob/main/cpp-client/deephaven/tests/src/table_test.cc

It's also possible that R is using the Arrow doPut call to push data to Deephaven directly. If so, that's outside the scope of this change and should already work.
I think I need to talk to @alexpeters1208 to make sure this provides what he needs.
