Klongpy

DuckDb to 0.9.2 (still limited to Python 3.11, 0.10.0 will have support for 3.12)
Min version of Python to 3.9 (because NumPy 1.26.4 is 3.9 to 3.12)

Improved multiline support and added transformer example.

While Klong automatically translates newline to semicolon, it was still required to have the closing } on functions to be on the same line (and also for arrays). We can now do something like:


nested::{[a b c fn];
a::x;
b::y;
c::z;
fn::{
x*x
};
fn(a+b+c)
}


which is a bit more conventional and easier to read.

A few upgrades since last release: Pandas 2.2.2 and DuckDB 1.0.

Some important bug fixes and simplified the internals for groupby.

Most notably, KlongPy can now call into python code that uses multiprocessing.

fixed negate which was creating a NumPy object array when negating an array - should be the base type in the array.
