[DevEx] Code gen - WIP

[xbtmatt]

Description

Probably needs its own repo at this point, but there are two big things here:

1. ABI Code Gen
2. New transaction builder flow with classes

ABI Code Gen

• Argument names
• Generated entry function payloads
• Separate into different files
• Separate into different folders for each module address
• Separate with namespaces
• Add ability to provide named address with config.yaml
• Export all generated code under namespaces in generated/index.ts
• [ ]More config.yaml options
• Add generated typescript doc comments
• Support scripts

Transaction Builder

• Fix assumptions around feepayer, need to set withFeePayer on instantiation
• Add MultiAgent support for transaction builder
• Couple the builder with ABI gen

TODO:

• Move typeTags out of external class arg types
• Move typeTags out of this.args and put a line below this.typeArgs = ...map()
• Change the input type for Option<T> to be undefined, null, or T instead of T | [T] or just all..?
• smart imports/exports. get rid of unused ones
• named addresses in typescript folder, rather than hardcoded module address in classes. That way it's easy to update the contract address once code has been generated
