too much memory cost when using preload

[williamfzc]

especially for long/high-quality video add hook for video object

[williamfzc]

from stagesepx.video import VideoObject
from stagesepx.hook import CompressHook

VIDEO_PATH = "demo.mp4"

v = VideoObject(VIDEO_PATH)
hook = CompressHook(target_size=(600, 800))
v.add_preload_hook(hook)
v.load_frames()

after that, all the frames would be converted to 600x800 before loading
