feat: flag for time/chrono crate support

[JoTurk]

Introduces a new --temporal option to choose temporal type mapping:

• raw (default): primitive types for backward compatibility
• time: uses time crate (time::Date, time::OffsetDateTime, time::Duration)
• chrono: uses chrono crate (chrono::NaiveDate, chrono::DateTime, etc.)
• Adds support for ClickHouse Time and Time64(precision) types.

Updated all snapshots.

We use this tool at my work, but difficult to work with for date & time types,
without using syn and quote. This patch solves it for us.

resolves #13

@abonander PTAL

[JoTurk]

@abonander I'm sorry for the ping, Just checking in to see if you've had a chance to review this. We've been using it for about a month.

[abonander]

Just wanted to trigger a CI re-run.

[JoTurk]

@abonander thank you for approving.
i force pushed to update my email :) I think the CI is failing because the integration test doesn't set a password or the password is incorrect. I can make a another PR to update the CI. but it's not related to this PR.

I've pinged our security team internally, I think the credentials just need to be rotated.

@loyd thank you for the review, I fixed the comments.

[abonander]

I didn't realize we don't actually run this CI against ClickHouse Cloud.

Try adding env: CLICKHOUSE_SKIP_USER_SETUP: 1 to the service definition here:

ch2rs/.github/workflows/ci.yml

Lines 45 to 49 in 0402177

	services:
	clickhouse:
