SFMS Insights: Green-up

**Describe the task**

Create an ON/OFF raster input for green-up status for deciduous and mixed wood fuel types.

**Acceptance Criteria**
- [ ] 2 provincial Julian Date static rasters, 1 for leaf on in spring, 1 for leaf off in fall, using julian date
- [ ] SFMS checks rundatetime, if date between spring and fall, it's leaf on, if outside the spring and fall, leaf off
- [ ] Reclassify fuel type grid according to leaf on/leaf off status (leaf on: d2/m2, leaf off: d1/,m1)

**Additional context**
- Add any other context about the task here.
- Or here

Start by locating the SFMS entry point for raster inputs, rundatetime handling, and fuel-type reclassification, then read the surrounding implementation and any existing raster tests. Done means adding the two provincial Julian Date rasters, determining leaf-on or leaf-off from rundatetime, and applying the specified d1/d2 and m1/m2 fuel mappings.
