int cast in add_dummy_markers to comply with blender python 3.1+

Overview

blenders python had some changes from 3.1+ that affect scripting, from docs:
https://wiki.blender.org/wiki/Reference/Release_Notes/3.1/Python_API
"Python 3.10 no longer implicitly converts floats to int's (issue linked). This means functions that previously accepted float typed values will raise a type error.
Floating point arguments must now be explicitly converted to integers"

This error is encountered in add_dummy_markers in nif_export/animation/init.py

A simple int cast resolves this - don't know if similar issues exists in other parts of the code. Should be harmless?

This is quirky as keyframes used to be able to land between physical frames, ie. needing floats rather than ints. The code that imports markers should be checked too.

Importing a nif with text keys in controllersequence wont give me any markers at all...

Nvm I'm stupid, they are there just fine - I just didnt show pose markers.

There already is a round statement in the code though, import_text_key_extra_data (nif_import/animation/__init__.py)has:

frame = round(key.time * self.fps)

Seems like the cleaner fix over just int casting...

Blenders bpy.types.Action's frame_range gives a [float,float] array - I think just casting these should be fine, afaik you cant set an actions start/end to sub-frame positions

added fix in get_controller_data -> see comment #506
