fix(python): reuse table state in write engine

[ion-elgreco]

Description

Instead of reusing the table state, it was being instantiated every time you call write with the rust engine.

• Expected number of requests to do a write #2448

Now we're cooking with gas!

Time to write tmp commit entry: 62.949541ms
Time to write final commit entry: 154.489917ms
Time taken: 0.5385329723358154
Time to write tmp commit entry: 102.603ms
Time to write final commit entry: 149.216375ms
Time taken: 0.5450408458709717

This immediately makes writes go a lot, lot faster 🥇!

Can we get this released asap?

[ion-elgreco]

@adriangb good to see :)

Let me see what I can do on the release.

Btw, one last question, did you see also these performance issues with the pyarrow engine? Because there we are reusing the state

[adriangb]

I did notice the pyarrow engine being faster in some cases, this seems like a likely culprit.
