cutout error fixed

[rishabhvarshney14]

related to #1227

I have tested these functions that used the apply_to_audio decorator

• with_start
• with_end
• with_duration
• subclip
• cutout
• loop
• time_mirror
• time_symmetrize

I have an issue with with_start. I am not sure what with_start suppose to do as compared to with_end with_start does not start with the expected starting time also time_mirror and time_symmetry gave error the same as here #1253.

Also in speedx.py it imports apply_to_audio and apply_to_mask but does not use it. Is this correct? Fixed

• I have provided code that clearly demonstrates the bug and that only works correctly when applying this fix
• I have formatted my code using black -t py36
