deprecation of _indices

[sjsrey]

xref #67

[jGaboardi]

Should we disable doctests for the _indices.py module to get CI green?

[martinfleis]

DeprecationWarning assumes that we cut a release, then change it to FutureWarning and make another release with that, then enforce the deprecation. Shall we rather go straight for FutureWarning?

[jGaboardi]

Good point, let's change to a FutureWarning.

[jGaboardi]

@sjsrey shall we pick this back up again to get CI green?

[martinfleis]

Slight issue I see is that this warning is emitted by import inequality even if you're not interacting with the indices module. We may need to emit it in the functions themselves. Maybe a decorator?

Looks like have a fresh exception being thrown by bleeding edge pandas now. If it's not something to simply let ride, we can open a new ticket for it.

We still need to address these failures, either by skipping or updating.

[martinfleis]

@jGaboardi that is fixed by geopandas/geopandas#3288
