Khalim Conn-Kowlessar 6b99ad0a55 heat_transmission: route exposed/semi-exposed floors through Table 20
SapFloorDimension gains an is_exposed_floor flag (default False) signalling
that the floor sits over outside air or unheated space rather than soil —
typical for an extension that hangs off the main from the first storey
upward (Elmhurst 000490 Extension 1 is exactly this shape).

heat_transmission_from_cert now consults the flag on the part's ground
SapFloorDimension and dispatches to u_exposed_floor (Table 20) instead
of the BS EN ISO 13370 / Table 19 cascade. Basement floor still wins
priority (Table 23 § 5.17 overrides everything else for that part).
