STD Crate Version Query

[crnbarr93]

Description

An ADO should be able to expose what andromeda-std crate version it is using, this will help in maintaining version updates.

Implementation

Add a query to ADOContract that responds with the contract's current imported version of andromeda-std:

pub enum AndromedaQuery {
  // ...
  #[returns(ADOBaseVersionResponse)]
  ADOBaseVersion {}
}

This should return a basic struct that contains the version:

pub struct ADOBaseVersion {
  // andromeda-std version in semver format
  version: String
}

Acceptance Criteria

• Added query to get the ADO's current andromeda-std version
• Unit testing for the query
