typegen issue with crux_http 0.7.0

[andrewweston]

I get the following error when generating types after upgrading to crux_http 0.7.0:

--- stderr
Error: type tracing failed: Not supported: deserialize_any:

An unsupported callback was called during (de)serialization tracing. In practice, this happens when an
unsupported Serde attribute is used. Attributes specific to self-describing formats (JSON, YAML, TOML)
are generally not supported. This includes: `#[serde(flatten)]`, `#[serde(tag = "type")]`, 
`#[serde(tag = "t", content = "c")]`, and `#[serde(untagged)]`.

I can trace it to the A::Capabilities::register_types(self) method but haven't had the time to dig further into it (yet).

Upgrading the counter example to use 0.7.0 gives the same issue.

I'm happy to pursue if the answer isn't immediately obvious.

Oof, sorry about that, I'll have a look at fixing it later today. It'll have something to do with the types introduced to the http capability protocol.

#207 should fix this problem. It does for the counter example. We'll release it later.

@andrewweston This should work with crux_http 0.7.1 again. Note that you need to add a line to trace the HttpError type like this:

gen.register_type::<HttpError>()?;

We'll be revisiting how typegen works to avoid these sorts of problems in the future (there's a tracking issue for that: #145)

Perfect, thank you.
