Your mission

Implement shift_letters, a Caesar-style letter shifter.

See it in action

shift_letters("margin", 4)

Expected result

"qevkmr"

Shift every alphabetic character by amount positions in the alphabet.
Preserve the original case of each shifted letter.
Wrap around after z and Z.
Leave non-alphabetic characters unchanged.
Support negative values and values larger than the alphabet length.
