Add wood harvest/products pool parameters to namelist file

CABLE

Thank you for submitting a pull request to the CABLE Project.

Description

The wood harvest/products parameters are hard coded into the CABLE-ACCESS interface. There is no technical reason to have these parameters hard coded and they are important for tuning the land use change/thinning components to get reasonable land-use emissions. I will move them into the CABLE namelist file.

These parameters are:

REAL :: pool_frac(3) = (/0.33,0.33,0.34/) !! Fraction of harvested biomass allocated to the wood products pools
REAL :: pool_time(3) = (/1.00,0.10,0.01/) !! Timescale of wood product pool decay to the atmosphere (year^-1)

Fixes #548

• Are the changes non bitwise-compatible with the main branch because of a bug fix or a feature being newly implemented or improved? If yes, add the link to the modelevaluation.org analysis versus the main branch or equivalent results below this line.

I just noticed that the namelist code is different in the CABLE repository and the UM7 repository. I might need to rethink this.
