Make new Uuid type Filterable

[kistz]

Description of Changes

Uuid addad in the last update is not filterable even though it is Copy and (imo) obviously very suited to filter.
Promote it to a special FilterableValue in the same way as Identity and adjust the docs.

API and ABI breaking changes

None

Expected complexity level and risk

1. Only copies the same strategy as Identity which is also a newtype wrapper around a integer like Uuid

Testing

Tested on my project.

Before the change:

You can also test this yourself when adding:
spacetimedb = { version = "1.11.2", git = "https://github.com/kistz/SpacetimeDB.git", branch = "uuid-as-filter" } to your cargo.toml project

• Tested before and after. Before it was a compiler error afterwards not.

Thank you for the submission. Unfortunately this is not sufficient to be able to merge this. We would need to implement this in:

• spacetime generate so the client can also filter
• C# (server/client)
• TypeScript (server/client)

It's important that we keep the various languages consistent with the features they support except in rare scenarios.

I can look into it today and/or tomorrow and let you know if i can get it to work :)
If not we can view this as an issue and close it/let someone from the team finish it 👍
