Make the Deadfish swim

Write a simple parser that will parse and run Deadfish.

Deadfish has 4 commands, each 1 character long:

• i increments the value (initially 0)
• d decrements the value
• s squares the value
• o outputs the value into the return array

Invalid characters should be ignored.

parse("iiisdoso") => [ 8, 64 ]
