User story

See ome/ngff#255

In this proposal (and in current SpatialData), coordinate transformations are defined in terms of input/output coordinate systems. Multiple coordinate transformations can be chained together. These chains can ultimately form a DAG representation.

We should define common functions in Viv for traversing this DAG and obtaining a path from a desired input and output system. If affine, this path can then be represented using a modelMatrix.

See the related vitessce/vitessce#1849

Should also continue to support the v0.4 and previous simpler transformation specs.

See in R this implementation which builds the DAG and provides a traversal function https://github.com/HelenaLC/SpatialData/blob/9885b6eedde155e6fb676b1f556e81b73093471c/R/coord.R#L31
