I have rebased this onto the main branch instead of Mark's PR so we have the option of landing this before or after that. I have added a unit test which checks the time warp effect type and linear |

Fixes jminor/otio-time-warp-test-suite#2
This PR attempts to fix the AAF->OTIO conversion of trim-to-fill time warp effects. Previously, they were translated as generic TimeEffects without any information (just a dump of AAF metadata). Now they are detected as LinearTimeWarp effects and a time_scalar is computed from keyframes and/or SpeedRatio.
Note, this PR is a draft. Further unit tests need to be added to verify correct behavior.
Also note that I did this work on top of @markreidvfx 's #44 but I believe this PR could be separated from that one, since the change is unrelated.
