Add tab to run browser for viewing area detector frames

[canismarko]

Things to do before merging:

• add tests
• write docs
• update iconfig_testing.toml
• flake8, black, and isort

Need to add a check to ensure that the first data array dimension matches the length of the time signal.

Not really understanding the framset_view part. I will test it in the real detector data.

Originally, all the tabs were just part of one big class (RunBrowserDisplay). This got harder and harder to maintain as we added more tabs.

To fix this, I took each tab and made it it's own class. If you open up run_browser.ui and look at what's inside of one of the tabs, you'll find that it's just an empty widget. Then there's a LineplotView class for the 1D line plot tab, and an associated lineplot_view.ui file. The LineplotView class is in charge of displaying the 1D line plot and managing the widgets for picking a signal to plot, reference corrections, calculating the derivative, etc.

FramesetView and frameset_view.ui are for managing the "Frames" tab, which displays area detector frames.

Here is the test using real Ge 8 element images:

1. It is difficult to choose a right ROI uisng mouse. Is it possilbe to input ROI center values to move the ROI square?
2. The data demension is 327, 8, 4096. Once uncheck 8, it should be the data of one element. Whiling choosing "Energy" as Time Signal, line plot should be the result of 1 element. But no line plot appeared below the image.
