Feature Request: ::new(_) should support .into()

[zutils]

Many times I have MyStruct::new("something".into()). I would rather not keep typing into(). Perhaps there is a way that new can take an Into.

I came to make the same suggestion.

However, I also prefer precision and explicitness, so I wouldn't recommend always supporting Into on every new param. Here are some brainstorms about design:

A per-struct style configuration

The default style equivalent to the current direct/concrete argument types, then a style called "Into" is introduced:

#[derive(new)]
#[new(style="Into")]
struct Account {
  name: String,
  info: Box<Address>,
}

let acct = Account::new("alice", Address::new(…));

Per-field configuration

#[derive(new)]
struct Account {
  #[new(style="Into")]
  name: String,
  info: Box<Address>,
}

let acct = Account::new("alice", Address::new(…)); // Error: expected `Box<Address>` found `Address`

My preference is to support both struct-scoped and per-field configurations. Struct-scoped reduces boilerplate, whereas per-field allows fined-grained precision.

I implemented the feature in #65 (first time contributor to this crate). Please let me know what you think.

This issue appears to have been resolved? #65 (comment)

The PR only implemented field attribute for into. So technically the request to additionally support it across all fields as a convenience still remains if relevant?
