FA support requires cy46_t1_op1.05/cy46t1_bf.07 of libs4py.so

Contents since 1.4.9:¶

(to get the same contents without element [13] => get v1.4.12)
(to get the same contents without elements [12],[13] => get v1.4.11)

• Invoke python3 explicitly in shebang

• Add get_inputs (for gallery) target in doc Makefile

• domain_making: threshold Lambert/Mercator raised to 5deg from equator

• [12] Pruning of basemap-based plotting functionalities and .cmap user-defined colormaps (use .json instead, cf. examples in doc). Include pruning of epy_plot.py
• contourf_kw, colorbar_kw and pcolormesh_kw arguments added to cartoplot method

• [13] FA: Upgrade libs4py.so to cy46_t1_op1.05/cy46t1_bf.07, in order to be able to read GRIB2-encoded FA/LAM fields, and fields with missing values in FA
• LFA/DDHLFA better distinction
• netCDFMNH: support for MNH 5.5.0
• FA: upgrade gribapi.def files to v32

• epyweb: web.py removed, to be installed with pip: pip3 install web.py

And a whole lot of various fixes...

Commit commit:478bf0ba

• Simplification regarding excludeextralevels parameter
• Correction in D3VirtualField.getlevel when level values are position dependent
• D3Geometry.isglobal property is added
• geoid was missing in geometry returned by make_section_geometry
