Implement transforms projection

[Fokko]

For evaluating the hibben partition filters, we need to have column projections. For example, this will translate dt <= 2024-02-01 and dt < 2024-03-01 to the partition filter month(dt) = 2024-02.

• And we need to port the project() method from the transforms: https://github.com/apache/iceberg-python/blob/main/pyiceberg/transforms.py
• Last, but most importantly, we need to port a ton of tests to make sure that this is implemented correctly: https://github.com/apache/iceberg-python/blob/main/tests/test_transforms.py

Does this duplicate to #264?

[viirya]

If not, I will work on this.

I think this issue includes several things, and they are tracked in #153 .

For this one, it looks like the same as #264.

Exactly, #264 is blocked by #283 , and @ZENOTME has a pr for it.

can this be closed - due to being a duplicate to #264 which was closed by #309?

Yes, we can close this, thanks @marvinlanhenke for this effort!
