Returns the median of the `[2nd list of commands]` when evaluated across all the turtles of breed frogs that satisfy the conditions (must return a boolean of true or false) specified by the `[1st list of commands]`.

Note: If `[2nd list of commands]` contains no numbers, an error occurs. If some of the `[2nd list of commands]`, when evaluated, are not numbers, those values are ignored.

Note: When a turtle calls the command, it is not included as part of the calculation.

Examples:
`median-of-frogs-with [color = red] [speed]` returns the median speed of all the red turtles of breed frogs.
