Implementation of arrays with metadata.

## Metadata Arrays

`MetadataArray` binds an array to named metadata.

```julia

julia> v = ["John", "John", "Jane", "Louise"];

julia> mdv = MetadataArray(v, groups = Dict("John" => "Treatment", "Louise" => "Placebo", "Jane" => "Placebo"))

4-element MetadataVector{String, Vector{String}, NamedTuple{(:groups,), Tuple{Dict{String, String}}}}:

 "John"

 "John"

 "Jane"

 "Louise"

julia> metadata(mdv, :groups)

Dict{String, String} with 3 entries:

  "John"   => "Treatment"

  "Jane"   => "Placebo"

  "Louise" => "Placebo"

```
