Biogas production (livestock --> dung --> biogas) (functions for each animal) (technology.py, biogas subclass)

[camiloramirezgo]

Calculate biogas production:

• From livestock maps estimate the amount of dung available
• Calculate biogas production based on reactor specs
• This will go in a Biogas sub-class of the Technology class.

A good methodology for biogas potential can be found in Dilip's paper: https://www-sciencedirect-com.focus.lib.kth.se/science/article/pii/S2213138821003118

Cropland residue is not feasible to be used for biogas production at a household level, as the technology is much more expensive and on a bigger scale.

There is more up to date information on livestock at the district level in Nepal. Dilip will share this data. That can be used directly or to calibrate the livestock datasets from FAO: http://www.fao.org/livestock-systems/global-distributions/en/
