Bug: get_energies does not always produce intended energy list

[PriyankaKetkarBNL]

In rsoxs_scans/constructor.py, the get_energies function does not consistently produce the desired energy list. Below are some examples of what is entered and outputs

energies = get_energies(edge=[260, 270, 280, 290, 293, 296, 300, 340], frames=1, ratios=[1, 1, 1, 1, 1, 1, 1]) 

## This works.  
## Output: [260. 270. 280. 290. 293. 296. 300. 340.]

energies = get_energies(edge=[282, 283, 286, 286.5, 287, 287.5, 288, 288.5, 289], frames=1, ratios=[1, 1, 1, 1, 1, 1, 1, 1]) 
## This works.  
## Output: [282.  283.  286.  286.5 287.  287.5 288.  288.5 289. ]

energies = get_energies(edge=[284, 284.5, 284.75, 285, 285.5], frames=1, ratios=[1, 1, 1, 1])  

## This doesn't work.

@PriyankaKetkarBNL I've been working on this and I think it would benefit from a complete refactor. We should decide how to best frame the custom energy scans to meet user needs.
