Description
This would be a nice feature to have for some use cases, e.g., for writing simulation time-steps:
https://stackoverflow.com/questions/46951981/create-and-write-xarray-dataarray-to-netcdf-in-chunks
It should be relatively straightforward to add, too, building on support for writing files with unlimited dimensions. User facing API would probably be a new keyword argument to to_netcdf(), e.g., extend='time' to indicate the extended dimension.

Research direction
Start with the existing support for writing files with unlimited dimensions and the to_netcdf() API, then review the linked Stack Overflow use case for chunked simulation time-step writes. Done means an existing netCDF file can be extended along a selected dimension, such as time, through the proposed API.
