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.

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.
