v0.17.0 does not work with Colab

[giswqs]

v0.16.0 works fine with Google Colab. However, v0.17.0 no longer works with Colab. The map does not show up.
Relevant issues:

• Can't show Map on Colab gee-community/geemap#1132
• ipyleaflet no long works in Colab googlecolab/colab-cdn-widget-manager#25

Maybe caused by #988 @jasongrout ?

[jasongrout]

Yes, it looks like an interaction between #988 (which depends on a feature of requirejs) and colab not using requirejs to load the AMD module. I'm following up at googlecolab/colab-cdn-widget-manager#25, so I'll close this issue in favor of that conversation.
