[ENG-4083] Add new trade constraints (#172) @edwardxtg

Added 4 new constraints to trade routes to control their absolute and percentage activity in a year:

activity_annual_max ({region:{region:{year:float}}}) - Maximum amount of a commodity that
can be traded in a year, in commodity units and for one direction (e.g. R1 to R2). This
constraint applies to commodities being exported, so does not account for trade losses.
Optional, defaults to None.

activity_annual_min ({region:{region:{year:float}}}) - Minimum amount of a commodity that
must be traded in a year, in commodity units and for one direction (e.g. R1 to R2). This
constraint applies to commodities being exported, so does not account for trade losses.
Optional, defaults to None.

availability_factor ({region:{region:{year:float}}}) - Availability factor for the trade
route, percentage given as a decimal ranging from 0 to 1 for one trade direction. I.e. the
fraction of the year that the trade route is available for use. Akin to availability_factor of
generation technologies.
Optional, defaults to None.

availability_factor_min ({region:{region:{year:float}}}) - Minimum availability factor for
the trade route, percentage given as a decimal ranging from 0 to 1 for one trade direction. I.e.
the minimum fraction of the year that the trade route must operate for.
Optional, defaults to None.

New feature region grouping v2 (#156) @djwels

This new feature allows a user to specifcy region groups which contain a set number of regions, to which a collective renewable target or emissions contraint can be applied. This allows such targets to be applied to a select few regions rather than the whole model.
