feat(bindings): bins(span | spanset, vsize, vorigin) table function

[estebanzimanyi]

Summary

Adds the first MobilityDuck TableFunction registration: `bins()` that partitions a span (or spanset) into uniformly-sized bins anchored at a given origin and emits one row per bin.

```sql
SELECT bin FROM bins(intspan '[1, 10)', 2, 0);
-- [0, 2)
-- [2, 4)
-- [4, 6)
-- [6, 8)
-- [8, 10)

SELECT bin FROM bins(tstzspan '[2000-01-01, 2000-01-04)',
INTERVAL '1 day',
TIMESTAMPTZ '2000-01-01');
-- [2000-01-01, 2000-01-02)
-- [2000-01-02, 2000-01-03)
-- [2000-01-03, 2000-01-04)
```

Coverage

10 overloads — every span / spanset base type:

Input	vsize	vorigin
`intspan` / `intspanset`	`INTEGER`	`INTEGER`
`bigintspan` / `bigintspanset`	`BIGINT`	`BIGINT`
`floatspan` / `floatspanset`	`DOUBLE`	`DOUBLE`
`datespan` / `datespanset`	`INTERVAL`	`DATE`
`tstzspan` / `tstzspanset`	`INTERVAL`	`TIMESTAMP_TZ`

Each overload returns a one-column relation `(bin )` matching the input's base type.

Implementation

Component	What it does
`BinsKind` enum	10-way tag dispatching to the right MEOS `*_bins` function.
`BinsBindData` (`FunctionData`)	Captures the three constant arguments at bind time and the chosen output span type.
`BinsInitGlobal`	Allocates the MEOS-managed `Span bins` array via the appropriate MEOS `_bins(s, vsize, vorigin, &count)` call.
`BinsExecute`	Emits up to `STANDARD_VECTOR_SIZE` rows per chunk; advances state offset.
`~BinsGlobalState`	Frees the MEOS-allocated array.

Date and timestamptz inputs are converted from DuckDB's 1970 epoch to MEOS's 2000 epoch via the existing `time_util.hpp` helpers. Output bins are stored in MEOS-native epoch form, which round-trips correctly through the span in/out functions.

This establishes the `bind` / `init_global` / `execute` scaffolding that follow-up table functions (`tsample`, `tprecision`, `similarityPath`, `tspatial_value/time_split`) can reuse.

Test plan

• All 10 overloads emit the expected bins for representative inputs
• Date / timestamptz round-trip correctly across the epoch boundary
• Chunk boundary handled (output stops at `STANDARD_VECTOR_SIZE`, advances offset for next chunk)
• Destructor frees the MEOS array
