uwapm seems broken after bokeh upgrade to 1.4

[harivnkochi]

I just upgraded bokeh to version 1.4, and I'm getting errors using uwapm (specifically, the create_env2d() function).

When I revert back to bokeh version 1.3, the error goes away.
I get the following warning

BokehDeprecationWarning: 'legend' keyword is deprecated, use explicit 'legend_label', 'legend_field', or 'legend_group' keywords instead

followed by the error:

Ah yes, bokeh changed the syntax. I will update in the upcoming release.

Line 398 also has the syntax "legend". It did not appear that you corrected this line in:
https://github.com/org-arl/arlpy/commit/6d1734cf5fd1439351a8221e57da5a8d6dfba49c

@rich9403 just checked ... there doesn't seem to be a legend= option on any Bokeh call anymore. The "legend" syntax for arlpy is still valid, and you pointed to a line where it was called on scatter? That is a arlpy function is supports option legend.
