Possibility of a meta context=="hydro"

[coxipi]

Addressing a Problem?

In xclim, we explicit define the "hydro" context.

hydro = pint.Context("hydro")
hydro.add_transformation(
    "[mass] / [length]**2",
    "[length]",
    lambda ureg, x: x / (1000 * ureg.kg / ureg.m**3),
)
...
units.add_context(hydro)

and then in lower levels, we have code snippets like:

    with units.context("hydro"):
       # perform operation

in various contexts.

I think we could support contexts explictly, maybe also define them in units, and then if users want a specific context, then can globally set:

with xsdba.units.units.context("hydro"): 
    xsdba.DetrendedQuantileMapping(...)

For xclim/xsdba users that are used to have context="hydro" activated presently, that would be useful.
