Jump Step should process all integrations at once

[stscijgbot-jp]

Issue JP-3550 was created on JIRA by Michael Regan:

Currently, the Jump step separately searches for jumps in each integration. For integrations with a relatively small number of groups (~<6) the result can be that jumps will not be masked.  

  In the case where there are multiple integrations, the code should use all of the integrations at once to identify the jumps. 

  This issue is related to help desk ticket INC0190775.

Comment by Melanie Clarke on JIRA:

Testing these changes on data with a small number of groups, from INC0197753, seems to have improved jump detection significantly compared to v1.13.4.  The sinusoidal artifacts mentioned in the ticket are no longer present in the final extracted spectrum.
