Confusing info in README

[garbofrogman]

In the current version of the README, the first line in the Demucs section of Full command-line interface options:
--demucs_segment_size DEMUCS_SEGMENT_SIZE Size of segments into which the audio is split, 1-100. Higher = slower but better quality (default: Default). Example: --demucs_segment_size=256

It doesn't specify what the default value is, and the example (256) is outside of the specified range (1-100).
