Reverse String

Instructions

Reverse a string

For example: input: "cool" output: "looc"

Bonus

Preserve grapheme clusters, i.e.

myreverse("hi 👋🏾") == "👋🏾 ih"
myreverse("as⃝df̅") == "f̅ds⃝a"

You will probably find the Unicode stdlib useful for this bonus task.

To enable the graphemes test, add const TEST_GRAPHEMES = true to the global scope of your file.
