Commit Message

feat: add `ChangeMembers::Batch(Vec<ChangeMembers>)` for batched membership changes

This commit introduces the `ChangeMembers::Batch(Vec<ChangeMembers>)`
variant, allowing `Raft::change_membership()` to accept an arbitrary
series of membership configuration changes as a single input command.
This enables users to define complex membership changes by combining
multiple `ChangeMembers` operations.

### Example:
The following example demonstrates removing nodes 1 and 2, and adding
node 3 in a two-step joint membership configuration change:

```rust
my_raft.change_membership(ChangeMembers::Batch(vec![
    ChangeMembers::RemoveVoters(btreeset! {1, 2}),
    ChangeMembers::AddVoters(btreemap! {3 => ()}),
]));
```
