more info in issue #67

Check and refactor project structure before resolving the issue

When the CMX parser finds an EDL rate mismatch, it reports 0.000000 instead of the rate the parser was using:

$ python3
Python 3.7.7 (default, Mar 10 2020, 15:43:03)
[Clang 11.0.0 (clang-1100.0.33.17)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import opentimelineio as otio
>>> otio.adapters.read_from_file("tests/sample_data/25fps.edl")
Trace

npm install 后运行报错了，麻烦可以告诉我这是什么原因造成的吗？
