Let users fix segmentation errors #59
Description
As of current, the segmentation as provided by the API service cannot be changed by the user. This leads to issues when a song mismatch occurs within a segment or segments are otherwise slightly off.
To resolve this, users should be able to manually change the start time and duration of segments.
Additionally, the audio API already provides a field called "mismatchOffsets" that includes offsets of segments at which a song mismatch occurred. These should be shown to the user to indicate that they should solve that mismatch.
