Yt slider limits not working

[mfoley-astro]

Describe the bug
The path to the UI file in slider.py needs to be changed to 'slider.ui', and the slider.ui file needs to be included in the glue-yt package. However, the slider is still not working when I try to use it in a time series. I am unable to move it and it doesn't return an error message, so it looks like the limits are not being set properly.

To Reproduce
Steps to reproduce the behavior such as:

1. Load in data file as a yt dataset
2. Make any plot
3. Click on 'Browse yt time series'
4. Slider will not slide or provide any error message.

Expected behavior
Yt has the ability to load in a time series object. This is done by providing a path to the files with some wildcard characters. You then can iterate through this object. The Glue Yt slider can load in a time series object and slide through it, reloading a single file for each value of the slider. The plot will then automatically update with the new data from the loaded file.

Details:

• Operating System: MacOS 10.15.1
• Python version (python --version): 3.7.5
• Glue version (glue --version): 0.15.6
• How you installed glue: Conda for glue and then pip for the glue-yt package
