next: Activating serialize feature on async-stripe-webhook results in compile error

[robko23]

Describe the bug

When enabling (de)serialize feature on async-stripe-webhook@next results in compilation error with messages that events don't implement serde::Serialize/serde::Deserialize.

My temporary fix to make it compile is this patch:

diff --git a/async-stripe-webhook/Cargo.toml b/async-stripe-webhook/Cargo.toml

+       "async-stripe-treasury/deserialize",
+]

but this enables all the optional crates and results in compiling code that I don't use elsewhere.

The solution would need to be in AND fashion, not OR.
Now the resolution works like this:

1. async-stripe-billing is optional and has feature serialize
2. enable async-stripe-billing on async-stripe-webhook -> crate enabled without serialize feature
3. enable serialize on async-stripe-webhook that has dependent feature async-stripe-billing/serialize -> crate also enabled with feature serialize even thought I don't need async-stripe-billing

The ideal solution would work like this:
async-stripe-webhook enables serialize AND async-stripe-billing.
this activates async-stripe-billing/serialize, but not the other crates.

Right now I don't have idea how to solve this, but that could just be my limited experience with cargo features.
If you have an idea how to solve it, I would be more than willing to open a PR to resolve this
