- update to 4.47.2:
* [merge] Improve help message and add standard command line
options
* [otlLib] Pass ttFont to name.addName in buildStatTable
* [featureVars] Re-use FeatureVariationRecord's when possible

- always obsolete fonttools. We have switched to python311 stack
in SLE15 and need to get the obsoletes back

to prevent XML External Entity (XXE) attacks (9f61271):
thus not participating in CFF2 delta computation, similarly to how
binary wheel is available for the given platform, e.g. pypy).
- update to 4.47.0:
* [varLib.models] New API for VariationModel: ``getMasterScalars``
and ``interpolateFromValuesAndScalars``.
* [varLib.interpolatable] Various bugfixes and rendering
improvements. In particular, add a Summary page in the front,
and an Index and Table-of-Contents in the back. Change the
page size to Letter.
* [Docs/designspaceLib] Defined a new ``public.fontInfo`` lib key,
not used anywhere yet (#3358).
* [featureVars] Allow to register the same set of substitution
rules to multiple features. The ``addFeatureVariations``
function can now take a list of featureTags; similarly, the
lib key 'com.github.fonttools.varLib.featureVarsFeatureTag' can
now take a comma-separateed string of feature tags (e.g.
"salt,ss01") instead of a single tag (#3360).
* [featureVars] Don't overwrite GSUB FeatureVariations, but append
new records to it for features which are not already there. But
raise ``VarLibError`` if the feature tag already has feature
