Deserialize Vec of Accounts

[armaniferrante]

Consider implementing the Accounts trait for Vec, where all accounts in the &[AccountInfo] slice are consumed and deserialized into the vec.

Trying to start with this good first issue.
How does that commit look ? CanardMandarin/anchor@bd5f815

Looks great. Let's add a test.

The remaining work here is to allow one to use Vec<Accounts> in the #[derive(Accounts)] struct and the client.

Hi, I was wondering where the derive(Accounts) for the Vec was coming/ if any help was wanted (as I need it for my current project).

I was also wondering which trait's need to be implemented in order to get Vec working in the derive. Currently, the error returned is just use of undeclared crate or module __client_accounts_vec

The reason for this error is due to the fact that it is treating the Vec as a composite field (Account<'info, SomeAccount>). Which I don't think is the result we want am I right @armaniferrante?

Any progress on this issue? Anything we could do to hammer it out?
