Map three more smart filters both ways in filterFX (smart_map.rs):
- Surface Blur: filterID 1135 (numeric), Fltr class `surfaceBlur`,
`Rds ` UnitFloat #Pxl -> radius, `Thsh` long -> threshold.
- Smart Blur: filterID `SmrB`, `Rds ` / `Thsh` doubles, `SmBQ` enum
(SBQL/SBQM/SBQH -> low/medium/high), `SmBM` enum
(SBMN/SBME/SBMO -> normal/edgeOnly/overlayEdge).
- Radial Blur: filterID `RdlB`, `Amnt` long, `BlrM` enum (Spn/Zm ->
spin/zoom), `BlrQ` enum (Drft/Gd/Bst -> draft/good/best).
Measured in Photoshop: applied through Action Manager to a smart object,
saved, filterFX read back. Every measured Fltr descriptor is written back
byte for byte (checked against the measured files locally; they are not
committed). Entries with missing keys, wrong types, out-of-range or NaN
values, unknown enum values or keys we don't model stay verbatim, as does
Radial Blur at its defaults (no Fltr stored). An off-centre Radial Blur
centre and unknown enum names are reported on save, not guessed.
