[Bug]: otio_reader.py using deprecated method

[markreidvfx]

What happened?

OpenTimeline v0.16.0+ changed the name of the following methods

clip_if() -> find_clips()
children_if -> find_children()

AcademySoftwareFoundation/OpenTimelineIO#1541

The otio plugin is using the old method name.

I think the only occurrence is here:

OpenRV/src/plugins/rv-packages/otio_reader/otio_reader.py

Line 284 in cebead2

for clip in tl.clip_if():
