Importing merge takes too long

[pablogamboa]

In my developer machine (M1 Ultra, SSD) import merge takes 1.7s. And it takes up to 5s in production (docker). This causes a significant slowdown in our app startup and the DX.

Can we do something about this? Perhaps this is related to #105.

python -X importtime -c "import merge" 2> merge.log
tuna merge.log

merge.log

Huge 👍🏻 to this. Merge is our slowest 3rd party dependency, taking many time longer than the next slowest one.
