Fix log message for GWSkyNet
There is a minor issue with the current log messages when running GWSkyNet:
GWSkyNet annotation from bayestar.multiorder.fits. GWSkyNet class score: 0.964, FAP:0.096, FNP:0.249. (gwskynet.json)
This should be instead (after adding some more spaces):
GWSkyNet annotation from bayestar.multiorder.fits. GWSkyNet class score: 0.964, FAP: 0.096, FNP: 0.249. (gwskynet.json)
