Build wgrib2 with NCEPLIBS-g2c for PNG + AEC decoder support 
The previous attempt to flip `-DUSE_PNG=ON -DUSE_AEC=ON` on wgrib2
broke the image build because wgrib2 v3.6.0's CMakeLists.txt
line 94 forces `find_package(g2c 1.9.0 REQUIRED)` whenever PNG or
JPEG2000 is enabled, and NCEPLIBS-g2c wasn't installed in the
wgrib2-builder stage.

Install NCEPLIBS-g2c v1.9.0 (the version wgrib2 asks for) in the
wgrib2-builder stage ahead of wgrib2 itself, with:

  - USE_PNG=ON           (needs libpng-dev, already present)
  - USE_AEC=ON           (needs libaec-dev, already present)
  - USE_Jasper=OFF       (default ON — would need libjasper-dev
                          and another runtime dep we don't need)
  - USE_OpenJPEG=OFF     (same rationale)
  - BUILD_G2C=OFF        (new experimental API, not needed here)

Then flip wgrib2's PNG/AEC flags back on. wgrib2's binary links
dynamically against libg2c.so so the final stage copies
/usr/local/lib/libg2c.so* from the builder and refreshes the
loader cache with ldconfig.

With the decoder restored, re-add MrmsFetchWorker to the prod
cron in runtime.exs. That worker pulls NOAA MRMS PrecipRate grids
every 2 minutes, which use GRIB2 DRT 5.41 (PNG-compressed) — the
whole reason we needed the PNG decoder in the first place. ASOS
nudges will now have a live radar overlay again.
