TimeSpan-Style TimeDuration Constructors in C# Bindings

[wes-sleeman]

Description of Changes

This change adds the following System.TimeSpan-style static construction methods to SpacetimeDB.TimeDuration:

• static TimeDuration FromMilliseconds(double milliseconds)
• static TimeDuration FromSeconds(double seconds)
• static TimeDuration FromMinutes(double minutes)
• static TimeDuration FromHours(double hours)
• static TimeDuration FromDays(double days)

These mirror the equivalently named static methods on System.TimeSpan and dramatically improve usability and familiarity for experienced C# users with no more overhead than the user performing the multiplication themselves.

Wish I'd thought to do this before v1.1.2 got released. Ah well.

API and ABI breaking changes

None. Convenience methods added in bindings only.

Expected complexity level and risk

1 (potentially up to a low 2 if cleanup is desired elsewhere in the bindings to leverage these new methods).

Testing

• Ensure the changes build.
• New contributor check! Review to make sure repo style & substance standards are complied with.

Thank you for submitting this! We'll work on getting it reviewed soon.

Thanks! Feel free to merge as-is if you have no problems with it on review. Also very happy to add the equivalent construction helper methods to the Timestamp class (based on the ones in System.DateTime) if that would be helpful? I can do it in this PR or just file a second one…

Hello! Just wanted to bump this as it's been a couple months now on what seems like a fairly minor edit. :)

[rekhoff]

These changes look reasonable and and clear.

I'm going to force-merge this since the only CI checks that haven't run/passed are from the public repos that we merged in. This PR is from before we merged them, so it can't mess them up.
