patch: fix rasterio 1.4.x regression

[bjlittle]

🚀 Pull Request

Description

This pull-request addresses a regression in the behaviour of the recently released rasterio 1.4.0 (and 1.4.1 patch).

For further details see rasterio/rasterio#3191.

Essentially geovista now explicitly manages the shape of data passed in and out of the rasterio.transform.xy function.

There was an implicit user assumption that rasterio would maintain the shape of data passed through rasterio.transform.xy, and this assumption held prior to 1.4.0.

rasterio 1.4.0 then enforced its expectation that data passed to rasterio.transform.xy was only 1-D.

The rasterio 1.4.1 patch reverted this regression in behaviour, thus allowing (for geovista) 2-D data to be passed into rasterio.transform.xy again. However, the resultant transformed data was no longer 2-D. This subsequently caused an issue for the geovista.bridge.

Rather than pin or wait for rasterio to possibly patch again, we now control the shape of the data ourselves.

Closes #1131
