Maintenance release with no intended changes to the API.

- Splits `compute_landuses()` function into separate `compute_accessibilities()` and `compute_mixed_uses()` functions.
- Adds deduplication to `compute_accessibilities()` and `compute_stats()`. This works through the new `data_id_col` parameter which, if set, ensures that only the first (nearest) datapoint location is considered. This is intended for situations where multiple data points represent a common feature (e.g. entrances to a building or a park).
- Exposes OSM API timeout parameter.
- Adds a `spatial_tolerance` parameter to `compute_accessibilities()` and `compute_mixed_uses()` functions. This flattens the spatial impedance curves used for data aggregation within the tolerance specified and is intended for situations where datapoints are located with a margin of imprecision. See `metrics.networks.distance_from_beta` for more information.

Resolves an edge case in graph consolidation workflows where a new node is located on top of an existing node.

Repurposes `io.osm_graph_from_poly_wgs` to `io.osm_graph_from_poly`:

- The input polygon's projection no longer has to be `4326` WGS, though this remains the default. It is now possible to specify other EPSG codes, e.g. `27700` if working with BNG.
- A `to_epsg_code` parameter has been added for specifying the output EPSG code. This is an optional parameter, and the behaviour will default to the local UTM CRS as per previous behaviour. If specified, the generated street network will be returned in the specified CRS.

Adds `nx_epsg_conversion` for converting networks from between specified EPSG CRS codes.

Refreshes docs and examples accordingly.

Minor tweaks and edge case handling in graph cleaning methods.

Adds continuity metric for "names", "routes", "highways" continuity, and a hybrid "names" and "routes" continuity.

Examples using OSM and OS Open data added to the [examples](https://cityseer.benchmarkurbanism.com/examples) page.

Addresses Shapely deprecation warnings for STR trees by adopting the new API.
