* Additional tests for straights

Additional tests for straights with the same tests also for straight flushes. (Originally proposed in the Rust track: exercism/rust#1555)

* Update canonical-data.json

remove trailing comma

* Update canonical-data.json

Add UUIDs generated by running "uuidgen".

* Reorder straight flush cases

This reorders the straight flush cases to match
the order of the straight cases, per suggestion from
petertseng.
