Description

This PR moves the existing TS SDK into a v0 directory and makes a new v1 directory for the new SDK. The v1 SDK is initially a copy of the v0 SDK, but the client code is regenerated and the wrapping SDK code is fixed accordingly.

Some other changes:

• Updated everything to work with the new lower snake case module names.
• Removed any deprecated functions, now is a good time.
• Updated most dependencies.
• Cut over to a better OpenAPI client generator, the one we're using for the v0 client is no longer maintained and outputs code that needs to be fixed up.

Still todo:

• Not only cut over all docs to point to a valid location, but rewrite them for the v1 SDK.
• Update all the comments for the wrapper functions in the SDK.
• Consider removing the wrapper functions from the SDK somehow, they're very thin.
• At this point I've updated all of the tests except those in the transaction builder.
• Clean up the GitHub actions, there's some duplication now.

Test Plan
