Marion scorage transposition fix

Problem: after artefact detection, the D.CRC.score structure is either in 8x1 or in 1x8 depending on Matlab version (8x1: Matlab 2015; 1x8: Matlab 2017). Only the D.CRC.score structure in 8x1 can be read by FASST.

Proposed changes of two scripts in the arousal detection folder:

• DC_artifact_COF.m: from line 76 to 92, add D.CRC.score{x,1} to be sure to create the D.CRC.score structure in 8x1 and comment the transposition of D.CRC.score (line 93)
• DC_extra.m: add C.CRC.score{5,1} (line 53) and C.CRC.score{6,1} (line 72) for the same reason than above and comment the transposition of C.CRC.score (line 73)
