support #[serde(alias)]

[anchpop]

Overview
#[serde(alias)] is a very useful attribute for maintaining backwards compatibility when renaming a field.

Requirements

1. tests
2. aliases should not show up unornamented in generated .did files

Considerations
There should not be any breaking changes, but generated .did files might become slightly less descriptive unless there is a way to automatically add a comment indicating aliases.
