///A builder struct for commands where you set multiple values at once. It utilizes
///references to ensure that it does not copy any of the data given to it. It supports
///the classic builder-pattern, as well as a mutable pattern.
///# Example
///```
///# use darkredis::MSetBuilder;
/// //Builder-style
///let mut builder = MSetBuilder::new().set(b"example-key", b"some-value");
///
/// // Mutable style
///builder.append(b"some-other-key", b"some-value");
///```
