Update CONVAIR & TWINOTTER CD's to v3.0.

Aircraft data analysis v3.0 upgrade from v2.1 includes:

1. A better IWC calculation which accounts for latent heat of fusion on the Nevzorov hot wire probe
2. Images of the ice crystal spectra for each 30-s case
3. Adjusted FSSP spectra which correct the LWC underestimate for the integrated spectra analysis
4. Quality controlled position data (latitude and longitude) at 10-second resolution which are correlated with the 30-second cases
5. Output of the total estimated ice crystal concentration for each 30-second case
6. Images of the flight tracks for each flight
7. Improved drop spectra analysis in mixed phase conditions
8. Reflectivity analysis for liquid phase hydrometeors (total and cumulative) (Rayleigh scattering approximation)
9. Crude Reflectivity analysis for ice phase hydrometeors (total and cumulative) (Rayleigh scattering approximation)
