Update 1D Profile viewer to use wcsaxes - Add slice function to 1D Profile viewer with sliders to select point

[nabobalis]

Rebase and update of #2167

As far as I can tell it this PR is meant to add:

Forces WCSAxes to be used for the .1D Profile viewer
A new slice function that allows a user to get the 1D data at a point
The slice function uses a new widget to allow selection of the point via two sliders

TODO:

• Slice sliders show up on x-axis change for other functions (go from slice to sum (or others), change x-axis, they appear)
• Fix tests
• WCS names are missing from x-axis dropdown, they are there on main.
• Profile is not displaying data when I change WCS axis name without moving the slider or normalizing the data

This needs fixing, I just have yet to work it out yet.
