The only thing working **bleep** this one is my laptop - lots of records! Also the whales I guess

There have been some really great challenges lately. I can't wait to do this one with my colleagues at work!

My solution is like many others, with the exception of pre-summarizing the whale data by whale ID and year. My general rule is always to reduce rows and columns as early as possible in a workflow, and that definitely made a difference with a dataset of this size.
 
Avg run time without pre-summarizing = 3.7 s
Avg run time with pre-summarizing = 2.7 s

I was also intrigued by @PhilipMannering and others' solutions using Find/Replace. I never would have thought to use that tool for this! On my laptop, it was a good bit slower, though (avg 5.9 s).
