Request for a new feature: Option to choose the size of the UMAP 2D fig

[remydecoupes]

Description: Could it be possible to add an option in order to fix the size of the UMAP 2D fig? Indeed, even if the bokeh app is in "scale_both" mode for "sizing_mode", the size of the left part of the app (i.e. the 2D fig) is fixed: plot_width = 300 (plot_width = 350 with color) and plot_height = 300. See in code

Option:

• As an example, the run command could be python -m bulk text [my_file.csv] -fig_size 700. It will fix plot_width and plot_height to 700.

Benefit:

• When the data points are very close, it becomes difficult to make a selection. Enlarging the figures allows us to better distinguish the points in order to select the ones we want.

I'm sorry, I have just seen this is a duplicated issue from #21
