Description of expected behavior and the observed behavior

As described at discourse, when trying to visualize Shuttle Radar Topography Mission data (SRTM, https://dwtkns.com/srtm30m/), the units come as a python tuple:

data = xr.open_rasterio("some.hgt")
data.units

When trying to hvplot this, data.sel(band=1).hvplot.image(), this yielded an error:

.../python3.9/site-packages/param/parameterized.py in _validate(self, val)
   1023 
   1024         if not isinstance(val, basestring):
-> 1025             raise ValueError("String '%s' only takes a string value."%self.name)
   1026 
   1027         if self.regex is not None and re.match(self.regex, val) is None:

ValueError: String 'unit' only takes a string value.

This issue had been created to add the ability to handle unit tuples.
