chore: change dsm hashing algorithm to match other tracers

[wconti27]

What does this PR do?

Makes DSM hashing consistent with other languages. Not a breaking change. Hashing algo has been changes to use fnv1 algorithm. The hashing code was based off the python implementation

LGTM at a glance, but I have a few questions before approving.

First, is this propagated horizontally, and if yes, wouldn't that be a breaking change?

Second, I thought the algorithm didn't matter which is why we went with the one that was simpler for the language. Has that changed?

The backend will handle that correctly, no matter which way the change is deployed.
It's true that the hashing algorithm is not critical, Node.js was the only one that was different though, so it's nice to have the consistency :)
