ROLLBACK: don't use "default (and optimized) predictor in `rasters.wr…

…ite` if SNAP is version 10 or higher" as it depends not on SNAP but on javax.imageio's version

 - ENH: Add a `BandType` alias for any types that could be a band: a string, a `BandNames` or any of its children: Spectral, SAR, DEM or Cloud band names 
 - FIX: Resolve the inversion of resolution and pixel size between `stripmap` and `sliding_spotlight` types for `Capella` products
 - FIX: Get better window name (if available) when writing bands on disk (in tmp folder) 
-- OPTIM: Use default (and optimized) predictor in `rasters.write` if SNAP is version 10 or higher ([#173](https://github.com/sertit/eoreader/issues/173))
 - OPTIM: Save rasterized masks of DIMAP V2 products on disk to avoid recomputing them (`features.rasterize` could be a heavy computation that shouldn't be done twice)
 - COMPAT: EOReader works correctly with SNAP 10 ([#165](https://github.com/sertit/eoreader/issues/165))
