### What kind of change does this PR introduce?

Improved the HBV-EC emulator by adding parameter information (name,
definition, and Raven default values) and fixed the variable name for
the adiabatic temperature lapse rate.

### Does this PR introduce a breaking change?

This should not introduce breaking changes, and any errors would be
captured by the tests already included in emulators.py.
