slice(instance, range)
Creates a new instance, with only a subset of the time periods.
This function does not modify the provided instance. The initial
conditions are also not modified.
Example
-------
```julia
# Build a 2-hour UC instance
instance = UnitCommitment.read_benchmark("matpower/case118/2017-02-01")
modified = UnitCommitment.slice(instance, 1:2)
