expose more functions from rust SDK

[wakamex]

things that would be useful for me right now:

• get_bonds_out_for_shares_in
• get_shares_out_for_bonds_in
• get_bonds_in_for_shares_out
• get_shares_in_for_bonds_out

please put your suggestions below.

These are all private functions in the yieldspace.rs library. What is the use case for making them public?

should we add something like the measure_value function into the rust SDK? https://github.com/delvtech/agent0/pull/1352/files#diff-588ee93bc3288ed7ed17a880e6ffdda7c986c72d22d289b23fbef3e2e0c07a4bR42

this predict function definitely feels like it should be in the rust SDK because it's very low-level https://github.com/delvtech/agent0/blob/a317f3d2fd0ece2627814a7d2368d6c87c52e9e4/src/agent0/core/hyperdrive/utilities/predict.py

I agree some of this can more heavily rely on the rust sdk. However, I think we should still avoid using any fns from yieldspace.rs. Instead, lets audit the agent0 _mock_contract.py file and ensure that all of the required high-level rust sdk functions are available (e.g. the fees can all be determined from rust now). We can then rewrite the predict.py and measure_value to use these higher-level functions.
