466bc8be0c Merge 'npm packaging for node and web' from Elijah Morgan 
Add web support to npm package.
**Still a WIP need to do some cleanup still**
I assumed it is better to keep the server code and web code together in
the same package (bigger download number). It took quite a bit of
experimentation but the ultimate experience is
node - commonjs
```js
const { Database } = require("limbo-wasm/node");
```
web - module
```js
const worker = new Worker(new URL('limbo-wasm/web/limbo-worker.js', import.meta.url), { type: 'module' });
```
Like I said this took a lot of experimentation on my part as this is my
first time trying to create an npm package let alone that mixes commonjs
and modules.
The structure is an npm workspace with two sub packages (web and node).
```

```
The output of wasm-pack gets put in <web/node>dist
JS code moves into <web/node>src/
Tests move under web/test
The npm package looks like (you can see I need to cleanup some of the
stuff that gets included).

f5e5428d45 Merge 'Syntactic improvements' from Jorge López Tello 
This is a purely syntactic PR. It doesn't change behavior, just rewrites
some loops and removes unneeded parts, like lifetime annotations and
references. Mainly because the Clippy and IDE warnings get annoying.
Don't worry about the number of commits, I just separated based on type
of change.

c8a979eb4b core: Move re-exports at top of lib.rs 
Clean up the code a bit by moving re-exports at the top of lib.rs to
make them more visible to the reader.

0561ff1545 Merge 'Fix scalar API in extensions, add documentation and error handling' from Preston Thorpe 
Closes #728
Changes the API to one macro/annotation on the relevant function
```rust
#[scalar(name = "uuid4_str", alias = "gen_random_uuid")]
fn uuid4_str(_args: &[Value]) -> Value {
    let uuid = uuid::Uuid::new_v4().to_string();
    Value::from_text(uuid)
}

register_extension! {
    scalars: { uuid4_str, uuid4 }
}
```
The only downside of this, is that for functions that use their
arguments, because this is not a trait, there is not really a way of
enforcing the function signature like there is with the other way.
Documentation has been added for this in the `scalar` macro, so
hopefully will not be an issue.
Also this PR cleans up the Aggregate API by changing the `args` and
`name` functions to constant associated types, as well as adds some
error handling and documentation.
```rust
impl AggFunc for Median {
    type State = Vec<f64>;
    const NAME: &'static str = "median";
    const ARGS: i32 = 1;

    fn step(state: &mut Self::State, args: &[Value]) {
        if let Some(val) = args.first().and_then(Value::to_float) {
            state.push(val);
        }
    }
//.. etc
```

3e28541b53 Merge 'Fix null compare operations not giving null' from Vrishabh 
In limbo when we do any compare operations like `Eq, gt, lt, gte, lte`
with nulls , we were actually giving the result as true where as sqlite3
gives null. This is because if we had a null, we were incorrectly going
to conditional branch and not increment program by 1. Also the sqlite
generates `ZeroOrNull` op in these cases
(https://github.com/sqlite/sqlite/blob/version-3.45.3/src/expr.c#L4644)
but we were generating a Integer instruction. The below outputs can give
a clearer picture.
This PR aims to fix this.
