[Bug]: Error + stack when missing keyframe at 0

Have you read the latest version of the FAQ?

[X] I have visited the FAQ page right now and my issue is not present there

Is there an existing issue for this?

[X] I have searched the existing issues and checked the recent builds/commits of both this extension and the webui

Are you using the latest version of the Deforum extension?

[X] I have Deforum updated to the lastest version and I still have the issue.

What happened?

Error if missing keyframe at 0 (I think this same trace can happen other ways too)

Traceback (most recent call last):

    if not value_is_number:
UnboundLocalError: local variable 'value_is_number' referenced before assignment

The error is this line, which is referencing value_is_number

I suspect the fix is just to indent that block, and just changing it to an else but I'm not too familiar with the intended behavior

Steps to reproduce the problem

Take default Deforum settings
Change any transform keyframe from a 0 to a 1
See error in logs and Deforum fails

What should have happened?

I would expect the first keyframe in the series, whether 0 or later, to dictate keyframes before
