Add IOPExample to HerbBenchmarks from HerbData

[THinnerichs]

"""
    struct IOPExample <: Example

An input-output example with an associated program.
`ex` is an [`IOExample`](@ref).
`program` is a program of arbitrary form. Please note that this is a pure container, and thus does not guarantee any checks on the validity of the program.
"""
struct IOPExample <: Example
    in::Dict{Symbol, Any}
    out::Any
    program::Any
end

was in HerbData, but should not be there. Add it to here.

Also adding reading and writing for these:

"""
    read_IOPexamples(filepath::AbstractString)::Vector{Tuple{IOPExample}

Reads serialized IO + program examples from disk after type checking.
"""
function read_IOPexamples(filepath::AbstractString)::Vector{IOPExample}
    @assert endswith(filepath, ".xiop")
    return deserialize(filepath)
end

"""
    write_IOPexamples(filepath::AbstractString, examples::Vector{Tuple{IOExample, Any}})

Writes IO examples and the corresponding programs to disk by serializing them into a file using HDF5 checking for and appending the `.xiop`.
"""
function write_IOPexamples(filepath::AbstractString, examples::Vector{IOPExample})
    serialize(filepath * (endswith(filepath, ".xiop") ? "" : ".xiop"), examples)
end

Do we actually still want this?

[sebdumancic]

I would say no because it is not a problem specification, just some handy structure
