Probabilities of single scenarios can be slightly above one as returned
by SCENRED2. Limit the probabilities to one.

Merge branch 'LossOfLargestInterconnector' into dev. Includes updates related to issues #69, #90, #91.

Removing q_resDemandLargestInfeedTransferUp and q_resDemandLargestInfeedTransferDown, as q_resDemandLargestInfeedTransfer can handle both.

Added new parameter `ts_energy_(s)` to which total energy is
calculated. This parameter has the sample dimension last, as required
by the SCENRED2 tool. This allowed changing all other time series
to have indices `s, f, t` instead of previous `f, t, s` and dropping
the set `fts` completely.

Fixes #105

Fixes #106

Only use scenarios with positive probability in building the long-term
stochastic tree. Previously this was limited to the number of scenarios,
but this allows excluding a scenario (setting its prob. to zero).

There were warnings about nested $ifthen structures and stray names
with spurious commas in symbol declarations.

Adding the grid dimension to the reserve parameters and variables. Changes required to the input files. Removing the obsolete nuft set. Issue #69.

Updating constraints for maximum share of reserve provision, ROCOF limit, as well as reserve demand caused by largest unit infeed and largest transfer link import/export. Testing one constraint for reserve demand caused by largest transfer link import/export (instead of two separate constraints).

See #102

The parameters were not cleared at every loop.

See #99

Removed now obsolete scalar `errorcount`.

Solves #102

Fixes #100

Set `gn_forecasts(*, node, timeseries)` tells for which grid/flow/restype, node and timeseries combinations use forecasts and by default includes everything.

See: #99

First tests, disabling all reserve requirement constraints except q_resDemand. Adding some new parameters and sets (df_reservesGroup, restypeDirectionGroup, restypeDirectionGridNodeGroup) and changing the dimensions of some other parameters, sets and variables.

Updating the two ROCOF constraints so that they apply to a group of nodes instead of individual nodes.

The transfer ROCOF constraint considers failures of interconnectors with one end inside the group and one end outside the group. 'DefaultFrequency' and 'ROCOF' are now p_groupPolicy parameters instead of p_gn parameters.

First try to fix issue #97.

Adding a new constraint q_maxDownward2 and modifying q_rampDownLimit. A small change to v_reserve.up to make it work with consumption units as well.

q_maxDownward2: similar to q_maxUpward2 but for v_gen and downward online+offline reserve provision

q_rampDownLimit: do not consider offline reserve provision

q_maxUpward: Moving "not nuOfflineRescapable(restype, node, unit)" from equation condition to a condition for summing reserve variables

q_maxUpward2: Removing many of the equation conditions (does not apply to consumption units, for example), cleaning up terms in the equation (hopefully not removing anything that should have stayed)

q_maxUpward3: Not sure if this constraint is needed, so ignoring it in invest and schedule models -- can be included again if needed

q_reserveProvision2: Some refinements to the equation conditions and the equation terms in order to make the constraint limit the online reserve provision of units with online variables

q_rampUpLimit: Moving "not nuOfflineRescapable(restype, node, unit)" from equation condition to a condition for summing reserve variables

q_rampUpLimit2: Not sure if this constraint is needed, so ignoring it in invest and schedule models -- can be included again if needed.

Also removed some non-existent features from the description
