Patch release needed to update pandas requirement

[YeChen-IDM]

In the Malaria Validation project, we are using a 3rd party library datar to manipulate our data in Python like dplyr in R. This library will need at least Pandas 1.2(pandas<2.0 and >=1.2) which is released on Dec. 2020. Currently Idmtools has a conflict on the Pandas dependency( idmtools 1.6.6 depends on pandas<1.2 and >=1.1.4).

Would it possible to update the Pandas requirement to at lease 1.2 in a patch release so we can use this 3rd party library?

Error about conflict dependencies when installing our package:

ERROR: Cannot install idmtools-cli and malaria-model-validation because these package versions have conflicting dependencies.
The conflict is caused by:
    datar 0.0.0 depends on pandas<2.0 and >=1.2
    plotnine 0.1.0 depends on pandas>=0.19.0
    idmtools 1.6.6 depends on pandas<1.2 and >=1.1.4
