Correct declared Python support and accept the 'id' field

[caglarpir]

Two small, independent correctness fixes to declared metadata and field validation.

1. REQUIRES_PYTHON was ">=3.0"

That is not satisfiable. The SDK cannot install on any Python 3.x below 3.10, because shapely>=2.1.0 — a declared runtime requirement — itself requires >=3.10. The constraint comes from the dependency set, not from the code: src/ contains no syntax newer than f-strings (no match, no PEP 604 unions, no walrus).

Verified empirically by installing the built wheel into clean environments and letting pip resolve install_requires:

Python	Result
3.9	fails to resolve (mapbox-vector-tile>=2.1.0 needs ≥3.9, shapely>=2.1.0 needs ≥3.10)
3.10	installs, SDK works end to end against the live API
3.12 / 3.13 / 3.14	install and pass the suite

Set to ">=3.10". Classifiers updated to match — 3.5 through 3.9 removed (none of them can install the package), 3.13 and 3.14 added, both verified.

2. id was rejected as a field

fields=["id"] raised InvalidFieldError, because id was absent from every entity field list — even though the Graph API accepts it and every decoded feature carries an id property. Confirmed against the live API:

GET /1933525276802129?fields=id,captured_at
{"id":"1933525276802129","captured_at":1507560881000}

GET /498808147909730?fields=id,object_value
{"id":"498808147909730","object_value":"object--street-light"}

Detections likewise return id. Added to the image, map feature, detection (both variants) and organization lists.

One caveat worth stating: images, map features and detections were each verified against the live API. Organization was not — I could not find an organization ID readable with the public test token. id is universal in the Graph API so it is near-certain to work there too, but I would rather flag it than imply I checked.

Test plan

• pytest — 17 passed
• flake8 src/mapillary --select=E9,F63,F7,F82 — 0
• SDK-generated URLs containing id verified against the live API (shown above)
• Differential dependency harness (41 probes): the only behavioural change is the intended field-list addition
