Is your feature request related to a problem? Please describe.
Indexer just got updated. SDK should be correspondingly updated.

Describe the solution you'd like
A way to generate the algonaut indexer sdk via the yaml file describing the algorand indexer api.

Additional context
Not aure what the update actually entails. I mostly heard about it through the grapevine.

https://github.com/algorand/indexer/blob/develop/api/indexer.oas3.yml

^ the OpenAPI config file.

I haven't had a chance to see if algonaut does any of that codegen stuff, so feel free to close if it does.

I was told that the initial indexer API was generated automatically, but I don't know how. To my knowledge, there's nothing in our code base to do this.

Noting that the generated code had some issues, like unnecessary use of Box, non ideal use of Option (e.g. when just a Vec makes more sense), lack of types (conversion to Address), etc. It might be possible to customize it.

@manuelmauro maybe you want to add something - just saw your OpenApi clients linked in #10. It might be worth going through e.g. https://openapi-generator.tech/docs/customization/ to see if it's possible to customize it to match our current more idiomatic API.

[manuelmauro]

Yes, I can confirm that I built the current API looking at Algorand's developer documentation and the generated OAS. But I tried to improve the ergonomics addressing issues like those @ivanschuetz highlighted in the previous comment.

Will be solved as part of #164 and #165
