Inner types of ignored external types are generated anyway

[gshep]

Problem

Not sufficient however would be nice to fix it. Generated Rust code contains redundant entities however they are inner types of ignored external ones.

Steps

1. the same as in Generated Rust code from idl with set external type requires PartialEq #556
2. generated idl_external_type_client.rs will contain the Inner struct. The file excerpt is attached.

Possible Solution

The basic idea is to make two passes. During the first pass populate inner external_types map. On the second pass the current logic is kept.

We can't skip generating types as IDL is used for generating clients not just for Rust, but for other languages as well where external Rust crates are unavailable

reopened since we discussed it in dm

A possible solution would be recursively marking a type as external provided it is referenced from another type marked as external.

It would be also nice to prefix such external types with pub
