Fix for blender 2.90.1 COLLADA exporter

[bmatthieu3]

It seems the COLLADA exporter from the new version of blender (2.90.1) adds a wrapper node named animation between library_animations and the list of bone animations. I am writing a library on top of this very good parser and this fix allowed me to open collada files from blender 2.90.1.
It is still not possible to export multiple animations inside one DAE file but that is another problem coming from the blender collada exporter I think.
The library is https://github.com/bmatthieu3/rib if you want to check.

Maybe this fix break importations from the previous blender versions

@bmatthieu3 can you fix the test test_get_animations? Run cargo test.

@bmatthieu3 is this still an issue?

Hi, I think this was due to a (maybe, this is what I deduced) from a breaking change in the way blender 2.90.1 serialize to collada comparatively to its previous version. Maybe a fix would be to parse the normal way and if its fails (exception) then try the "2.90.1" way. Le sam. 4 sept. 2021 à 23:15, Sven Nilsen ***@***.***> a écrit :
