Separate channel output in MCT

[hannahlanzrath]

While the outlet can be split up into individual channels, via SPLIT_PORTS_DATA, this is not possible for the bulk solution.
Since the different channels are not a continuous radial direction of the model, but individual compartments, we should separate the solution output for the channels.

Todo

• Delete flag SPLIT_PORTS_DATA, they should alsways be split up
• Export bulk solution per channel/port, similar to outlet i.e. SOLUTION_BULK_PORT_000

Providing the bulk solution for each channel separately

Thats already possible by specifying SPLIT_PORTS_DATA = 1

[hannahlanzrath]

Currently SPLIT_PORTS_DATA = 1 only influences the solution of inlet and outlet, not of the bulk solution.
