Support Sequences

[SimonIT]

I'm currently developing a crate for creating WireGuard configurations. Here is an example:

           [Interface]
           PrivateKey = yAnz5TF+lXXJte14tji3zlMNq+hd2rYUIgJBgB3fBmk=
           ListenPort = 51820

           [Peer]
           PublicKey = xTIBA5rboUvnH4htodjb6e697QjLERt1NAB4mZqp8Dg=
           Endpoint = 192.95.5.67:1234
           AllowedIPs = 10.192.122.3/32, 10.192.124.1/24

           [Peer]
           PublicKey = TrMvSoP4jYQlY6RIzBgbssQqY3vxI2Pi+y71lOWWXX0=
           Endpoint = [2607:5300:60:6b0::c05f:543]:2468
           AllowedIPs = 10.192.122.4/32, 192.168.0.0/16

           [Peer]
           PublicKey = gN65BkIKy1eCE9pP1wdc8ROUtkHLF2PfAqYdyYBz6EA=
           Endpoint = test.wireguard.com:18981
           AllowedIPs = 10.10.10.230/32

There are multiple peer sections. Naturally, I would have a type Vec<Peer> for them.

There is also an AllowedIPs entry for which I would have a type Vec<IpNetwork>.

It would be great if support for multiple sections was available. Perhaps it could be configured to specify how a sequence should be serialized?

This is currently my workaround: https://github.com/SimonIT/wg_config_file/blob/170a088dbf6b5e2bb215a1da22214069ad4c0120/src/lib.rs#L34-L42. It would be much easier if this were supported directly.
