Investigate using otoole to read in OSeMOSYS datafile

[willu47]

otoole uses the Amply package to read a GNU Math Prog datafile into a Python dict of pandas DataFrames.

For example

from otoole.read_strategies import ReadDatafile

filepath = 'path/to/kenya.txt'
strategy = ReadDatafile()
osemosys_model, default_values = strategy.read(filepath)

This might be a nice way then edit the model, by adding new rows to the pandas dataframes and then writing out the model using a write strategy:

from otoole.write_strategies import WriteDatafile

filepath = 'path/to/kenya_gis.txt'
strategy = WriteDatafile()
strategy.write(filepath, osemosys_model, default_values)

Ok. Maybe we can have a chat about this. It sounds good, and follows the current OSeMOSYS workflow.
