Debug pulse based pad

Hi @amohammadi

Again, I had to do some modifications to my pulse-based PAD code ... I modified the handling of landmarks detector failing, since it does not raise an error anymore, but returns None.

Anyway, everything's green so I guess that you can merge this.

BTW, let me know if it annoys you to be assigned for each change I'm making ... I understood that it was a good practice not to auto-merge to master ... But since it may happen quite often in the near future, I don't mind doing it ;)

Like last MR, I cannot look deeply into these kind of changes so you can merge it yourself without assigning to me.

Will do (and for potential future modifications too), and sorry to bother you with this ;)

merged
