Bug fix for direction in readCapytaine

[akeeste]

This PR solves #997 and updates:

• readCapytaine to convert direction from radians (Capytaine's convention) to degrees (WEC-Sim's convention)
• updates examples/BEMIO/Capytaine scripts to use radians, not degrees
• updates examples/BEMIO/Capytaine results

[dforbush2]

Looks good to me, fixes the wave direction input in Capytaine input to be in radians in example runs, and fixes readCapytaine to convert radian capytaine output to be in degrees, as appropriate for WEC-Sim. Addresses #997

[dforbush2]

only outstanding item is to update run capytaine results with the new input files.

@akeeste would you be able to re-run the example files and push corrected outputs or should I? Be good to merge this ASAP

[akeeste]

@dforbush2 I am running the OSWEC example now and then will finish up the last too expensive cases (RM3, COER_COMP). Should be done soon.

@dforbush2 the new output data is complete and all my tasks are finished on this PR. In addition to the tasks above, I added minor clean-up on the headers that Spyder puts in python files by default. This is good to go on my end
