Research direction

No files or tests are named. Start by tracing the DataArray.pint.to("nm") accessor and reviewing how Pint contexts and decorators accept variables; clarify whether upstream Pint support is required. Done would mean an agreed API and tests showing a context variable can be obtained from the current DataArray coordinate.

Written by the indexing model from the issue text.

Description

For example, consider the spectroscopy context:

@context(n=1) spectroscopy = sp

There the conversion depends on the variable n used. Now, consider a DataArray/DataSet where n is a dimension/coordinate. Then when calling DataArray.pint.to("nm") we would want the variable n to be dynamically imported from the current context of the DataArray coordinate.

API-wise I am not sure how that would work, maybe by passing a list/dict of context objects (+ variables)? This might also involve upstream pint support for more complicated context and decorators.
